摘　　要：根据相变机理将定形相变材料分为固-固相变材料(SSPCM)和形状稳定相变材料(FSPCM)两大类,进而按材料组成将SSPCM分作有机和无机两类,按载体材料不同将形状稳定相变材料分作聚合物FSPCM和多孔材料FSPCM两类,并分别介绍了各类定型相变材料所包含的物质种类、性能特点,叙述了各类材料的研究现状。总结了定形相变材料的制备方法,包括物理吸附法、熔融共混法、微胶囊化及压制烧结法4种。指出定形相变材料的应用领域,以及在定形相变材料研究和应用中存在的问题。In this paper, according to phase transition mechanism, the so-called shape stabilized phase change materials are classified as solid-solid phase change materials （SSPCM） and form stable phase change materials （FSPCM）. S SPCM cover organic and inorganic ones according to materials＇ composition FSPCM include polymeric and porous material matrix ones due to different carder materials. Phase change materials mentioned above and their unique performances are further introduced. Research development is summarized. Preparation methods, i.e. adsorption, congruent melting, micro-encapsulation and pressing-sintering, are reviewed. Application fields of shape stabilized phase change materials are presented. Existing problems in the study and application of SSPCM and FSPCM are pointed out.
