一种新型的固-固相转变材料的合成、表征及性能研究

摘要

A novel polyethylene glycol (PEG) functional compound was obtained from the end-groups modification of PEG. The com-position and structure of the PEG functional compound were characterized by IR, 1H NMR. The novel Eu-PEG polymeric solid-solid phase change luminescence material (Eu-PEG PSSPCM) was prepared with the coordination reaction of the PEG functional compound and Eu3+. The composition and structure, phase change properties were researched via IR spectra, DSC curve. The results show that the Eu-PEG PSSPCM possesses steady chemical structure and excellent phase change properties.%通过聚乙二醇端基改性,合成了一种新形的聚乙二醇功能化合物.其组成结构通过红外、核磁进行了表征.利用合成的新形聚乙二醇功能化合物与三价铕离子的配位作用,获得了一种新形的Eu-PEG聚合物基周-固相转变材料.该种固-固相转变材料的组成结构和相变特性通过红外光谱和DSC曲线进行了表征.结果显示该种固固相转变材料拥有较好的相转变特性.
