【Abstract】 The clothing containing phase change material(PCM) with function of absorbing the body-released heat has wide applications. In this paper, preparation a novel cooling sodium sulfate based phase change material was investigated. The results show that PCM posses suitable melting temperature,large heat flow,stability after repeating applications, and the PCM is convenient for application and effective in cooling. Moreover, the manufacturing process has a great affect on the property of the titled material.更多还原
