Résumé

In this paper, graphene/paraffin/EVA PCMs (GrPrE) was prepared by melting, blending and ultrasonic dispersion method with a series of graphene mass fraction of 0.05%,0.1%,0.25%, and 0.5%. The physical properties of GrPrE were characterized by SEM, DSC, and Hot-Disk. The experimental equipment of heat storage tester was built to test the thermal efficiency and performance of GrPrE during the energy storage process. The result showed that the GrPrE had a good performance in dispersion and stability. The temperature and latent heat of phase transition had no significant change. The thermal conductivity increased with the increasing of graphene mass fraction. In the thermal storage test, the heat transfer rate of the graphene-added materials was faster than the unadded materials, the material which the proportion of graphene was 0.1% had the best performance in the test. In summary, the composite can be a potential candidate for thermal storage applications due to the good thermal properties and heat transfer performance.
