Abstract

Summary form only given. Polypyrrole(PPy) is one of the most stables conducting polymers due to its high thermostability and life stability. In general, it has been known that PPy films can be synthesize by anodic electropolymerization, oxidative chemical polymerization and plasma enhanced polymerization. We have synthesized polypyrrole(PPy) nanofilms using vapor-phase oxidative polymerization process in a vacuum chamber under ultraviolet (UV) photon irradiation. That time, we measure the current through conducting polymer connected with two electrodes by Kiethley 2400 multimeter. Vapor-phase polymerization techniques for the preparation of PPy of nanofilm type require that pretreated substrates be essentially activated with inhibitor. In this case, an insulating substrate is pretreated with polymer containing electron acceptors and initiators such as ferric chloride. PPy nanofilm that was irradiated by UV photon are rapidly synthesized and current of two electrodes increased. These PPy nanofilms are characterized by atomic force microscopy (AFM), Raman spectroscopy, Fourier-transform infrared spectroscopy (FT-IR) and field emission scanning electro microscopy (FE-SEM). Possible mechanism is proposed for the formation of the PPy nanostructure during the vapor-phase oxidative polymerization

外场对聚吡咯聚合的影响

只提供摘要形式。聚吡咯(PPy)具有较高的热稳定性和寿命稳定性，是最稳定的导电聚合物之一。总的来说，已知聚吡啶薄膜可以通过阳极电聚合、氧化化学聚合和等离子体增强聚合三种方法合成。采用气相氧化聚合法制备了聚吡咯(PPy)纳米膜。当时，我们用基思利2400万用表通过两个电极连接的导电聚合物测量电流。气相聚合法制备纳米膜型聚吡啶的技术要求预处理的底物基本上被抑制剂激活。在这种情况下，用含有电子受体和引发剂如氯化铁的聚合物对绝缘衬底进行预处理。紫外光子辐照后的聚吡啶纳米膜快速合成，两电极电流增大。采用原子力显微镜(AFM)、拉曼光谱(Raman)、傅里叶变换红外光谱(FT-IR)和场发射扫描电镜(FE-SEM)对聚吡啶吡啶纳米膜进行了表征。提出了气相氧化聚合过程中聚吡啶纳米结构形成的可能机理
