Abstract
Abstract In this work, the thermal performance of graphene reinforced paraffin wax phase change material (GrPW-PCM) for thermal energy storage applications has been investigated. Though a stability test for the confirmation of uniform dispersion of graphene in paraffin wax environment is conducted but scanning electron microscopy (SEM), Fourier transform infrared spectra scope (FTIR) and thermal conductivity are also applied to characterize the microstructure, chemical structure and thermal properties. Four different samples of GrPW-NC phase change material (PCM) are prepared with a low mass fraction of graphene varied from 0.0 to 2.0 wt.%. However, the best performance with regards to thermal conductivity is given by 2.0 wt.% GrPW-PCM nanocomposites, which has been improved 66.15% when compared with pure paraffin PCM.
