淀粉基聚氨酯疏水材料的制备及其降解性能
|
摘要
首先通过聚乙二醇(PEG)与六亚甲基二异氰酸酯(HDI)反应制备了异氰酸酯接枝的聚乙二醇(PEGiso)。然后将PEG-iso以不同的比例加入到玉米淀粉(HAGS)中,制备了淀粉基聚氨酯(HAGS-PEG-PU)复合材料。通过红外光谱(FTIR)、扫描电子显微镜(SEM)、差示扫描量热分析(DSC)、热失重分析(TG)及接触角测试等手段研究了HAGS-PEG-PU的结构及其热性能、降解性能及疏水性能。
Polyethylene glycol grafted by isocyanate( PEG-iso) was prepared by the reaction of PEG and hexamethylene diisocyanate( HDI) firstly. Then the prepared PEG-iso was added into corn starch( HAGS) with different proportions and obtained starch-based polyurethane composites( HAGS-PEG-PU).The structure, thermal properties, degradation and hydrophobic properties of HAGS-PEG-PU composites were studied by FTIR,SEM,DSC,TG and contact angle measurements.
