超疏水材料的防水性能表明它们适用于许多应用。然而,有机粘结剂已被广泛用于制备超疏水表面,而无机粘结剂的应用报道较少。采用无机粘结剂磷酸铝(AP)将TiO2纳米颗粒粘接在基体上,然后用十二烷基三甲氧基硅烷(DTMS)进行改性,得到TiO2/AP@DTMS超疏水涂层。采用扫描电镜(SEM)、热重(TG)和接触角测量方法研究了TiO2/AP@DTMS超疏水材料的性能。结果表明:超疏水表面表现出高的热稳定性和耐有机溶剂性。此外,TiO2/AP@DTMS超疏水涂层具有良好的自清洁性能,可用于负载,最大负载量为99.35g。可用于水油分离和乳化液分离,在含油废水处理中具有很好的应用前景。
The waterproofing properties of superhydrophobic materials suggest that they are suitable for numerous applications.However,organic binders have been widely employed to prepare superhydrophobic surfaces,while inorganic binder applications are less reported.Here,TiO2/AP@DTMS superhydrophobic coatings were obtained through bonding TiO2 nanoparticles to the substrates using inorganic binder aluminium phosphate (AP),followed by modification with dodecyltrimethoxysilane (DTMS).The properties of TiO2/AP@DTMS superhydrophobic materials were investigated with SEM,TG,and contact angle measurement.The results showed that the superhydrophobic surface exhibited high thermal stability and resistance to organic solvents.Moreover,the TiO2/AP@DTMS superhydrophobic coatings demonstrated favorable self-cleaning properties and were available for load carrying,with a maximum load capacity of 99.35g.It was also effective in water-oil separation and emulsion separation,indicating a very promising prospect in the processing of oil-containing wastewater.
