摘要
结合科研工作热点和学科前沿方向,该文设计了"SA/rGO@CuS光热转化复合相变材料制备及性能研究"综合性实验。将具有光吸收能力的硫化铜(CuS)纳米粒子负载在具有高导热系数的还原氧化石墨烯(rGO)上,制备得到rGO@CuS复合物,以其为载体材料负载相变芯材十八酸(SA),设计制备出具有光捕集、光热转换和定形相变储能于一体的SA/rGO@CuS复合相变材料。通过扫描电镜、透射电镜、拉曼光谱仪、X射线衍射仪、傅里叶变换红外光谱仪、差示扫描量热仪等,对其进行结构表征及性能测试。本实验在培养学生掌握基本实验操作技术的同时,能够提升其逻辑分析能力和对科学研究的热情。
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.
