【摘要】 <正> 0 前言稀土金属因其独特外层构型而表现出特殊性质而引起广泛应用。若以有机高分子为基体,将稀土金属引入合成聚合物-稀土金属离子配合物,既能保持有机高分子材料原有性能又能体现稀土金属的某些性质。由于天然产物漆酚的聚合膜具有良好的抗老化性能和机械性能,我们以漆酚为基体,通过电化学聚合方法得到聚合漆酚(EPU),利用其苯环上两个-OH邻酚羟基为供电基团与稀土金属络合,合成一系列新型的电化学聚合金属配合物。可望应用于高分子功能膜材料、化学传感器、导电高分子材料等方面。作者合成了电化学聚合漆酚-铁配合物(EPU—Fe3+),采用X光电子能谱、红外光谱、ESR、荧光光谱、动态机械热分析(DMTA)和元素分析法表征该配合物膜,并分析了配合物可能存在的结构。更多还原

【Abstract】 The iron eleclropolyurushiol chelate compound (EPU-Fe3+) was obtained by the reaction between iron chloride isopropyl alcohol solution with electropolyurushiol (EPU). The properties of chelate compound film were characterized by XPS, FT-IR, ESR, DMTA, fluorescence spectrum and elementary analysis. The results indicated that coordination occurred between EPU and Fe3+, thus cross-links were formed, and intermolecular forces enlarged DMTA analysis showed that there were two glass transition temperatures in the chelate compound. The temperatures increased and resistance to heat was enhanced considerably.更多还原
