    Self-lubricating polytetrafluoroethylene/polyether ether ketone (PTFE/PEEK) composites for robot joint bearings were prepared by fused deposition modeling (FDM) process and hot-pressing sintering processes,and the materials were further modified by heat treatment.The effects of the various heat treatment stages (warming,holding and cooling) on the tribological properties of the materials were explored by single-factor test method.The experimental results showed that the heat treatment modification could significantly improve the tribological properties of PTFE/PEEK composites molded by FDM and hot-pressing sintering processes,but the temperature increase rate should be reasonably controlled,and too fast heating rate could easily lead to insufficient crystallization of the material and deteriorate the effect of the modification.The tribological properties of the specimens prepared at a heating rate of 2℃/min were optimal.The optimal holding temperature for FDM and hot-pressing sintered specimens were 210℃ and 205℃,respectively,and too high temperature was prone to induce brittle transformation of the material and deteriorate the tribological properties.Compared with the cooling method of quench cooling,the natural cooling could reduce the stress and other structural defects inside PTFE/PEEK materials due to cooling,which could reduce the friction factor of FDM molding specimens by about 16.81% and that of hot-pressing sintered specimens by 11.65%,endowing the materials with better tribological properties.

    Aramid pulp (AP) has excellent mechanical properties and heat resistance,but its effective dispersion in polymer matrix has always been a difficult problem.In this paper,aramid pulp was modified by phosphoric acid acidification and silane coupling agent grafting techniques.Aramid pulp/nitrile rubber (AP/NBR) composites were prepared by open mill mixing method.The effects of surface modification methods on the mechanical and tribological properties of composites were studied.The experimental results showed that phosphoric acid treatment significantly improved the degree of fibrillation and surface roughness of the pulp.After grafting modification with silane coupling agent,aramid pulp formed aggregates again.Acid-modified aramid pulp (a-AP) could effectively improve the elastic modulus of the composites.The comprehensive properties of the nitrile rubber composites prepared with silane coupling agent-modified aramid pulp (g-AP) were more excellent,which was because the surface modification of aramid pulp effectively improved the interfacial bonding strength of the composites.

    Constructing a special structure on the surface is one of the main methods to improve electromagnetic impedance matching of carbon materials and thus to achieve materials with “thin,wide,light,and strong” electromagnetic absorption characteristics.The lightweight dendritic carbon nanotubes@boron nitride (CNT@BNNOs) composites were prepared by in-situ pyrolytic polymerization of ammonia borane (AB) and high-temperature sintering.The structure,morphology,elemental composition and electromagnetic parameters of the materials were characterized and tested by X-ray diffractometer,field emission scanning electron microscope,X-ray photoelectron spectrometer and network vector analyzer.The results showed that the introduction of boron nitride (BNNOs) improved the agglomeration phenomenon of carbon nanotubes (CNT) and generated a large number of heterogeneous interfaces and defects,which greatly optimized the impedance matching of the material and thus enhanced the microwave absorption characteristics of the material,while retaining the physical properties of CNT such as lightweight and highly stability.CNT@BNNOs-2 achieved a minimum reflection loss (RLmin) of -36dB at 14.4GHz,and the effective absorptionbandwidth (EAB) reached 5.04GHz (microwave effective absorption band of 11.92～16.96GHz) at a coating thickness of 2mm.CNT@BNNOs-4 achieved an EAB of 5.68GHz (microwave effective absorption band of 3.6～7.28GHz and 16～18GHz) at a coating thickness of 5.8mm.

    The continuous emission of volatile organic compounds (VOCs) not only leads to serious environmental problems but also poses a significant threat to human health.Photothermal catalytic oxidation of VOCs is considered as a green and sustainable technology.Therefore,excellent catalysts are needed to efficiently utilize solar energy and drive catalytic reactions.In this work,NiCo2O4/attapulgite(ATP) composite was synthesized using ATP as support through an sol-gel method.The presence of Ni ions changed the charge transfer mechanism and interacted with Co ions through capturing excited electrons,thereby generating excellent light absorption capacity.Under light irradiation,the 1∶5 NiCo2O4/ATP catalyst absorbed visible and infrared light,induced lattice vibrations,and ultimately converted photon energy into heat,alllowing it to achieve excellent photothermal conversion performance (195.6℃) without additional heating.The introduction of ATP promoted the formation of an efficient NiCo2O4/ATP interface and generated abundant oxygen vacancies that acted as adsorption activation centers to convert absorbed O2 molecules into reactive oxygen species,thereby promoting the degradation of toluene.The 1∶5 NiCo2O4/ATP catalyst achieved 82% toluene degradation at an initial concentration of 500×10-6.This work provides a new strategy for cost-effective photothermal degradation of VOCs.

    A series of GdVO4∶Yb3+,Er3+/Tm3+ phosphors were prepared by co-precipitation method.The stureture,morphology and upconversion luminescence were characterized by X-ray diffraction (XRD),scanning electron microscopy (SEM) and upconversion emission spectroscopy.The effects of doping ions concentration and excitation power on the luminescence properties were investigated.The results showed that the synthesized phosphors were GdVO4 with tetragonal structure.The rare-earth ions doping had no impact on the crystal structure.However,high Yb3+ ions doping concentration could cause the decrease of interplanar spacing.The morphologies of the samples exhibited an uniform spherical particles with slight agglomeration.The samples emitted green and blue upconversion luminescence from Er3+ and Tm3+ ions,respectively,under the excitation of 980nm infrared light.GdVO4∶10%Yb3+,1%Er3+ and GdVO4∶10%Yb3+,0.75Tm3+ phosphors had strong upconversion luminescence intensity.High rare-earth ions doping concentrations resulted in lower luminescence efficiency due to cross-relaxation processes.The color coordinates of the samples indicated that the color of the luminescent color of the phosphors could be tuned by changing the concentration of doped rare-earth ions and the excitation power.

    Water pollution is severe worldwide,and there is an urgent need to develop effective technologies for water purification.4-nitrophenol (4-NP)is a common pollutant that can be reduced to the pharmaceutical raw material 4-aminophenol,which can create value while purifying water.Transition metal nanoparticles are commonly used in catalytic reduction reactions,but their tendency to aggregate affects catalytic activity.Loading metal nanoparticles onto porous carbon materials doped with heteroatoms can stabilize metal nanoparticles and improve catalytic efficiency.In this work,a simple and effective strategy was employed to prepare nitrogen- and oxygen-doped carbon nanosheets by direct pyrolysis in air using a molten salt-assisted method without the need for a precision tube furnace.The obtained carbon nanosheets were used as carriers for the growth of small-sized and uniformly loaded Co nanoparticles to prepare catalysts Co NPs/NOC.The optimal preparation conditions for catalyzing the reduction of 4-NP with NaBH4 were found to be using ammonium oxalate as the nitrogen source,a 1∶1 ratio of carbon source to nitrogen source,pyrolysis temperature of 700℃,and cobalt salt addition of 3mL.The catalyst prepared under these conditions achieved an apparent rate constant of 0.00632s-1 and maintained a 90% conversion rate after five cycles.

    To enhance the functionality of styrene-butadiene-styrene (SBS) modified asphalt,nano-ZnO and nano-TiO2 were used for composite modification of SBS-modified asphalt.The physical and rheological properties of the modified asphalt were investigated through three indexes,temperature scanning,and low-temperature creep tests.Microscopic analysis was carried out using infrared spectrometer and a fluorescence microscope.The results revealed that as the nano-ZnO and nano-TiO2 content increased,the penetration of nano ZnO/TiO2/SBS composite modified asphalt reduced,while the softening point increased,and the high-temperature performance was markedly enhanced.In addition,the complex shear modulus and rutting factor of increased,while the phase angle substantially declined,indicating improved rutting resistance.The best performance was achieved at 3% ZnO and 4% TiO2 content.As the nano-modifier content elevated,the ductility of the ZnO/TiO2/SBS composite modified asphalt reduced,stiffness modulus rose,creep rate diminished,and the low-temperature performance slightly declined.Compared to base asphalt,new absorption peaks were observed in SBS modified asphalt,signifying a chemical modification by SBS.In contrast,the nano-ZnO/TiO2/SBS composite modified asphalt didn't exhibit any new absorption peaks,indicating that the modification by nano-ZnO and TiO2 belonged to physical modification.

    Esterified lignin (PA-L) was prepared using cotton stem lignin (LG) and propionic anhydride (PA) as raw materials,and the effects of different dosages of LG and PA-L on the properties of SBS-modified asphalt were investigated.The performance of LG before and after modification was analyzed by thermogravimetric analysis (TG),Fourier transform infrared spectroscopy (FT-IR),and contact angle analyzer (OCA).The basic physical properties of the composite modified asphalt were analyzed using three major indicators,and temperature scanning and multiple stress creep recovery experiments (MSCR) were conducted on the composite modified asphalt using a dynamic shear rheometer (DSR).The results showed that the modification of PA-L was successful,and the hydrophobicity and compatibility with asphalt of the modified PA-L were significantly improved.PA-L improved the high-temperature stability of SBS-modified asphalt and had a smaller weakening effect on its low-temperature crack resistance.Its optimal dosage was 5%.Compared to LG,the modified PA-L had better thermal stability,greater hardness when blended into SBS-modified asphalt,more linear changes in various indicators,larger complex shear modulus (G*),smoother phase angle,better stability and rutting resistance,as well as better creep recovery ability.

    As global climate warming and environmental issues becoming increasingly severe,CO2 emission reduction and resource utilization have become focal points in academic research.This study focused on optimizing the performance of Fe-based catalysts in CO2 hydrogenation reactions,particularly the impacts of carrier surface functional groups on catalytic activity and product selectivity.Through the hydrothermal synthesis,nanocarbon spheres with different surface microenvironments were synthesized,and by combining with the equal-volume impregnation method to load metal active components and promoters,a series of Fe-based catalysts were successfully prepared.The catalysts were characterized by scanning electron microscopy (SEM),X-ray Diffraction (XRD),transmission electron microscopy (TEM),X-ray photoelectron spectroscopy (XPS),and in-situ diffuse reflectance infrared Fourier transform spectroscopy (DRIFTS),and the results revealed that the carrier surface functional groups had a significant impact on the CO2 conversion and product selectivity,providing new insights for designing efficient and stable Fe-based catalysts.

    Rice husk biochar was used as the raw material,modified with magnesium and loaded with nitrogen and phosphorus to obtain a composite biochar material,struvite@rice husk biochar composite (MARC),for adsorbing Cr(Ⅵ) in wastewater.The characterization of MARC showed that struvite formed on the surface of MARC,which possessed abundant functional groups including —OH,—COOH,—NH,—PO3-4 and Mg—O.The adsorption capacity of Cr(Ⅵ) by MARC reached 20.14mg/L at 25℃ and pH value of 4.5.The conditions of lower temperature and pH value favored the adsorption.The adsorption process of Cr(Ⅵ) by MARC followed the Freundlich model and the pseudo-second-order model,indicating the multi-layer chemical adsorption of non-uniform surface.“Killing three birds with one stone” tactic was achieved for the simultaneous utilization of agricultural waste as the raw material of biochar to enhance resource utilization,the nitrogen and phosphorus sourced from N-P containing wastewater to alleviate water eutrophication,and the enhancement of the Cr(Ⅵ) adsorption via the generated struvite.
