Melamine foam (MF) is an ideal material for encapsulating solid-liquid phase change materials.Molybdenum disulfide (MoS2) nanoparticles were adhered to the MF framework using polydimethylsiloxane (PDMS),followed by carbonization and adsorption of polyethylene glycol-6000 (PEG-6000) to form composite phase change materials (CMFP-X MoS2@PEG).The composition,morphology,energy storage density,and thermal cycling stability of CMFP-X MoS2@PEG were analyzed using scanning electron microscopy (SEM),Fourier-transform infrared spectroscopy (FT-IR),X-ray diffraction (XRD),and differential scanning calorimetry (DSC).The thermal conductivity and photothermal conversion performance of the samples were tested using thermal infrared imaging and temperature measurement instruments.The results showed that MoS2 nanoparticles were uniformly distributed on the foam framework.CMFP-X MoS2@PEG exhibited high energy storage density,excellent leak-proof performance,and photothermal conversion efficiency exceeding 90%,indicating potential applications in solar energy collection and thermal therapy fields.
