摘要/Abstract

摘要： 采用物理共混和化学方法合成了PEG/PET固固相转变材料（PCM），这种材料在能量储存和温度控制领域有广泛的应用。不同制品对材料的相变性能要求不同。通过对合成方法、交联体系、PEG的相对分子质量及不同相对分子质量PEG共晶和PEG/PET的配比等影响因素的调节来控制该材料的相变性能。

Abstract: PEG(polyethylene glycol)-PET(polyester) was prepared by both grafting PEG to PET chemically and blending physically. Such phase change materials (PCM) have extensive application in energy storage and temperature control. In order to meet the requirements for different products，synthesis methods，the molecular weight of PEG，weight percentage of PEG/PET and co-crystallization of different molecular weight of PEG. synergy of PEGs with different molecular weights，and crosslinking system are the factors used to regulate the phase change behavior of the phase change material.
