电化学聚合漆酚稀土配合物的合成与表征
Study on the Coordination Polymer of Electropolyurushiol and Rare Earth
【摘要】 采用电化学方法合成的聚合漆酚( EPU)与三异丙氧基稀土 Re (Pr, Nd, Eu)反应,生成稀土金属配合物 (EPU- Re3+ ).利用 FT- IR、荧光光谱、 XPS、 DMTA、 AES等手段对其表征,探讨其结构与性质 .证明了配合物中存在着稀土金属离子 Re3+与 EPU的配位作用,并引起进一步的交联,因而难溶于绝大多数有机溶剂,而且其玻璃化转变温度和耐热性能均得到提高 .
【Abstract】 The coordination polymer of rare earth was prepared by the reaction of rare earth triisopropoxide(Pr, Nd, Eu) with electropolyurushiol polymerization(EPU). The structure and properties of the coordination polymer were characteized by FT- IR,Fluorescence, XPS, DMTA and AES. The results indicated that there is of coordination interaction between rare earth ion with electropolyurushiol in the coordination polymer, thus cross- link was formed. Therefore the coordination polymer was insoluble in most organic solvents, and glass transition temperature increase and heat resistance were enhanced considerably.
