Abstract:Stearic acid/silicon dioxide composite material is prepared by sol_gel method. Its structure and properties have been studied with TEM, SEM, and DSC. The result shows that it's successful to prepare the phase change composite material and it is 3_dimension meshy nano_composite and it has favorable heat capacity. It can be used in the application of solar energy and some other applications.
Keywords:sol_gel method  phase change composite material  thermal energy storage
