复合相变材料研究进展

Progress in studies of phase change composites

复合相变材料主要指性质相似的二元或多元化合物的一般混合体系或低共熔体系,形状稳定的固液相变材料,无机有机复合相变材料等。因其独特的功能成为近来新材料研究的热点。介绍了较为常见的几种复合相变材料的制备方法,溶胶凝胶法、加热共熔法、多孔介质法,微胶囊法,高分子聚合法等,并对它们的特点进行了分析,最后介绍了复合相变材料的前景。

Phase change composites are the normal mixed systems or low eutectic systems which are composed of binary mixture or multicomponent mixture whose characters are in similar conditions, and the materials which are distinct by the phase change between solid and liquid, and the ones which are the distinct by such change between inorganic and organic composite . By virtue of their distinguish functions, the composites phase change materials have been a highpoint of the relevant new material researches. In this paper, several kinds of meth- ods, such as sol-gel process, eutectic process, porous medium process, microcapsules process, and macromole- cule process, which are able to bring out those phase change composites are introduced, and the characters of those methods are reviewed generally. In the end of this paper, the authors give an outlook for the promising future of the phase change composites.
