Abstract

Low thermal conductivity and liquid phase leakage impede the widespread adoption of phase change materials (PCMs). To enhance PCM performance and practical viability, addressing these limitations is crucial. Current study addresses low thermal conductivity and leakage issues. Enhanced thermal conductivity in PCMs is achieved by adding graphene nanoplatelets (GnPs), while expanded graphite (EG) acts as a leak-proof barrier. The composite PCM (ss-NePCM) composite is developed by ultra-sonication followed by vacuum impregnation process. The samples underwent comprehensive analysis: thermal conductivity (TEMPOs), chemical composition (FTIR), photo-transmittance (UV–Vis), and thermal stability (TGA). The results show that the composite with 0.6 wt% GnP (NePCM3) has the highest thermal conductivity enhancement of ≈112% while adding 15 wt% EG (ss-NePCM3) diminishes leakage problem. According to the optical performance assessment, the composite exhibits a notable increase in absorbance of 116% higher than that of the base PCM. However, due to the introduction of additives, the differential scanning calorimeter (DSC) detected a minor variation from 154 to 144.76 J g−1 in the latent heat. Furthermore, the composite demonstrates chemical stability and thermal reliability following 250 heating and cooling cycles. The ss-NePCM holds promise for thermal systems, where leakage could jeopardize system integrity.
