| Abstract: | Based on the hot spot of scientific research and the frontier direction of the discipline, the comprehensive experiment on preparation and properties of SA/rGO@CuS photo thermal conversion composite phase change materials is designed. The rGO@CuS compound is obtained by decorating Cu S nanoparticles with high light absorption capacity onto the reduced graphene oxide(rGO). The SA/rGO@CuS composite phase change materials are designed and prepared by loading stearic acid(SA) into the support. The structure and properties are characterized by SEM, TEM, Raman spectrometer, X-ray diffractometer, Fourier transform infrared spectrometer, differential scanning calorimeter, etc. This experiment can not only train students to master the basic experimental operation technology, but also improve their logical analysis ability and enthusiasm for scientific research. |
