In this paper,carbon coated aluminum nanoparticles were prepared by direct current discharge method.Carbon coated aluminum/paraffin wax phase-change composites were fabricated by dispersing the carbon-coated aluminum nanoparticles in the paraffin wax(PW)matrix.X-ray diffraction(XRD),scanning electron microscope(SEM)and transmission electron microscope(TEM)analysis methods were employed to investigate the morphology and microstructure of carbon-coated aluminum nanoparticles.The thermal properties,thermal sta...
