通过电化学方法合成的聚合漆酚 (EPU) ,与氯化镨作用生成聚合漆酚 镨配合物膜。采用原子发射光谱、红外光谱、荧光光谱、差热 热重分析、X光电子能谱和动态机械热分析等手段进行表征。探讨其结构与耐热性质。证明了螯合物中存在Pr3+和EPU的配位作用 ,并引起进一步交联 ,因而难溶于绝大多数有机溶剂 ,同时玻璃化转变温度和耐热性能均得到提高。
Electrochemically synthesized polymerized urushiol (EPU) is reacted with praseodymium chloride to form a polymeric urushiol praseodymium complex membrane. Atomic emission spectroscopy, infrared spectroscopy, fluorescence spectroscopy, differential thermal gravimetric analysis, X-ray photoelectron spectroscopy and dynamic mechanical thermal analysis methods were characterized. Discuss its structure and heat-resistant properties. It is proved that there exists coordination between Pr3 + and EPU in the chelate and leads to further cross-linking. As a result, it is hardly soluble in most organic solvents, and the glass transition temperature and heat resistance are improved.
