A mixture of polyethylene glycol and stearic acid is developed to extend the working temperature range and improve the heat utilization efficiency, and composited with carbonized loofah sponge fragments using melt impregnation method to improve the thermal conductivity of solid-liquid phase change material and find a solution for its leakage issue. The combination of different components, thermal stability, phase change behavior, thermal conductivity, shape stability, temperature response time and application cost are investigated. The results ...
