探讨了漆酚 (EPU)的电化学聚合及其聚合漆酚 镍配合物 (EPU_Ni2 +)的制备 .采用X光电子能谱、红外光谱、动态机械热分析 (DMTA)、TG_DTA、原子发射光谱 (AES)等手段对配合物(EPU_Ni2 +进行表征 .AES结果表明 :镍含量达 7.5 % .由于存在着Ni2 +与EPU的配位作用 ,并引起进一步交联 ,从而提高了玻璃化转变温度和耐热性能
The nickel electropolyurushiol coordination polymer(EPU Ni 2+ ) was obtained by the reaction between nickel chloride isopropyl alcohol solution with electropolyurushiol (EPU).The electrochemical polymerization of urushiol and the preparation of nickel electropolyurushiol coordination polymer were investigated.The coordination polymer was characterized by XPS,FT_IR,DMTA and AES methods,and its composition and structure were determined.The content of Ni 2+ reached up to 7.5%. It was shown that there was certain coordination between Ni 2+ and electropolyurushiol in the coordination polymer,thus cross_links were formed.Therefore the glass transition temperature of the coordination polymer increased and heat resistance was enhanced considerably.
