摘要
采用原位聚合法制备了MWNTs—COOH/PU复合导电薄膜.FT-IR分析证明MWNTs—COOH与聚氨酯间形成了氢键;POM和XRD分析表明,实验制备的聚氨酯样品中存在着由软、硬段微区形成的微相分离结构,并且因氢键作用使固化薄膜中硬段微区形成有序结构而产生一定的结晶.紫外光谱分析证明,MWNTs—COOH与聚合物之间的氢键相互作用对聚合物的电子结构也产生影响.
MWNTs -COOH/PU composite conductive thin films were prepared by in-situ poly-merization. FT-IR analysis demonstrated that and the hydrogen bond are formed between MWNTs-COOH and polyurethane. POM and XRD analysis showed that polyurethane samples prepared the sample,and there was a microphase separation structure formed by soft and hard segment microdomains in the experiment. Due to hydrogen bonding, the hard segments in the cured films formed ordered structure and produced a certain crystallization. UV-spectrum analysis shows that the hydrogen bonding interaction between MWNTs-COOH and polymer has an in-fluence on the electronic structure of polymer.
