摘要： 用2,4-甲苯二异氰酸酯将蓖麻油及聚乙二醇(PEG)偶联成聚氨酯,同时通过自由基聚合使2-乙烯基吡啶(VP)与蓖麻油的双键共聚,生成互穿网络聚合物(IPN),其产率及凝胶含量大多超过93%,力学性能很好.当IPN与LiClO4络合后呈现离子导电现象;与TCNE或TCNQ络合后产生电子导电,与LiClO4及TCNE(TCNQ)络合后,呈现比上述两种导电率更大且具有协同效应的混合导电率,在25℃混合电导率可达到10-3～10-2S/cm.

Abstract: Interpenetrating polymer network was synthesized via reaction of castor oil, poly(ethylene glycol), toluene 2,4-diisocyanante and 2-vinyl pyridine in the presence of redox initiator and dibutyl tin dilaurate as the catalyst. Both yield and gel content of most IPNs are higher than 93%. The IPN was characterized by IR spectrum and gel content. The IPM obtained exhibits good mechanical properties, which are related with its crystallinity. When the IPN is complexed with LiClO4, it exhibits an ion-conductivity, whereas when it is complexed with TCNE or TCNQ, it shows an electronic conductivity. When the IPN is complexed with both LiClO4 and TCNE or TCNQ, it shows a mixed conductivity with a synergistic effect, i.e. the mixed conductivity is higher than either electronic conductivity or ionic conductivity. The mixed conductivity can reach 10-3—10-2S/cm at room temperature.

Key words: Interpenetrating polymer networks, Ionic conductivity, Electronic conductivity, Castor oil polyurethane, Poly(vinyl pyridine)
