Energy depletion for the thermal regulation of buildings is a major global concern. Herein, we develop a binary eutectic phase change material (EPCM) consisting of sodium sulphate decahydrate (SSD) and sodium phosphate dibasic dodecahydrate (SPDD) that were modified using borax, carboxymethyl cellulose (CMC), and graphene nanoplatelets (GNP).
The basic properties of a phase change material are the phase change temperature and latent heat [6]. Transfer of thermal energy in a phase change material occurs during the phase change process from one phase to another phase [7]. Phase changes in these materials are separated into solid-solid, solid-liquid, and solid-gas.
