摘要：

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 of GA affecting the properties of SSPCMs were explored. The results show that GA in the SSPCMs not only can greatly improve the thermal conductivity of SSPCMs, but also can reduce its the leakage rate. And as the structure of GA is more regular, its leakage rate is lower. The existence of GA, to some extent, makes SSPCMs have higher enthalpy. © 2017, Editorial Board of Polymer Materials Science & Engineering. All right reserved.
