Different morphologies of graphene aerogel(GA) were prepared by controlling different reaction temperature via in situ self-assembly method. Paraffin/GA shape-stable phase change materials(SSPCMs) with higher thermal conductivity,higher energy storage capacity and lower leakage rate were prepared by the vacuum impregnation method.Microstructure,thermal property and leakage rate of SSPCMs were studied by SEM,DSC,thermal conductivity analyzer and leakage rate testing. And the addition of GA and the morphology...
