Characterisation and thermophysical properties of graphene nanoparticles dispersed erythritol PCM for medium temperature thermal energy storage applications
Abstract
Thermophysical properties of graphene dispersed erythritol PCM (NDPCM) analysed. FTIR spectrum confirmed graphene nanoparticles integrated well into erythritol PCM. DSC results revealed less change in latent heat and phase change temperature after 100 thermal cycles. 1 wt. % graphene increases thermal conductivity by 53.1% with only 6.1% decrease in latent heat of erythritol. Addition of graphene has a positive influence, i.e. the degree of subcooling is reduced.
