| 摘 要： | 采用化学改性的方法,将不同含量,不同分子量的聚乙二醇(PEG)接枝到以聚醚型的聚氨酯(PU)上,制备出一种新型的固-固相变材料。并通过红外光谱法(IR),示差扫描量热法(DSC)来研究合成材料的结构与相变行为。结果表明,PEG成功地接枝在高分子链PU上,且具有较好的相变焓,适合的相变温度,并当PEG分子量相同时,随着PEG含量的增加,相变材料相变焓增大,热切热稳定性有明显改善,当PEG含量相同,PEG分子量在600～2000时,随着分子量的增加,材料的相变焓增大。

| Abstract: | Different content and molecular weight of PEG were grafted onto the polymer chain of Polyurethane(PU) which was synthesized by polyether and TDI.Then the solid-solid polymer phase-changed material was prepared. Material phase-change behavior and structure were investigated by DSC,IR.The results indicated that the PEG was successfully grafted onto PU.When the molecular weight of PEG kept sameness.The phase change enthalpy of material would be increased by improving the PEG content,and thermal stability was o... |
