Abstract
This study synthesized modified graphite (EG) through the ultrasonic dispersion method in brewed wine solution with myristic acid (MA) to create conduction of heat mechanism with a greater affinity for saturated fats. The resulting EG made a fatty acid hybrid phase change material (PCM) with excellent overall thermal behaviour. Fourier transform infrared spectroscopy, and X-ray diffraction showed that the synthesis involved physical adsorption rather than a chemical reaction. Differential scanning calorimetry studies showed that adding EG boosted the heat capacity of the hybrid PCM after 1000 heat storage and release cycles. Melting and freezing latent temperatures were 196.99 kJ/kg and 195.33 kJ/kg. Using thermogravimetric analysis (TGA), the thermal stability of MA/EG was evaluated. The SEM findings demonstrate effectively that EG uniformly surrounds the myristic acid's multi-pore structure and that the MA/EG is mostly silky. This revolutionary approach permits the development of hybrid phase-change composites with heat exchange abilities, high conductivity, and excellent thermal stability, which can be applied in a various energy storage technologies.
