Extraction of natural piperine crystals from black pepper with expanded graphite for thermal energy storage

Abstract

Substantial research was done on the synthesis of piperine crystals (PC) from black pepper using expanding graphite (EG) as a promising organic phase change material (O-PCM). Researchers examined the chemical structure and thermal properties of the substance. Using the diffusion–exudation circle method, the PC/EG-blended PCM had the highest PC mass content, at 93.4 %. According to (DSC) study, the melting and crystallization temperatures are 135.6 °C and 117.4 °C, and their related latent energies are 283.14 KJ/kg and 192.45 KJ/kg. This finding implies that the material retains a respectable capacity for heat storage after being exposed to multiple heat patterns. Thermal storage/discharge studies revealed that the EG/PC material had much better heat storage/discharge ratios than the PC sample. At ambient circumstances, our findings indicated that the Herbal Piperine crystals/expandable graphite PCM was a superior thermal energy storage medium. The results demonstrated that the proposed hybrid composite can be considered as a potential solar energy storage material for a variety of applications, including thermal cooling of photovoltaic panels, automobiles, digital units, solar residential heating systems, and passive solar heating systems.
