中文摘要:

在磅的吸水的组采用磅电影方法,多层的磅电影被选择的 arachidic 酸(AA )/PEDOT,和 polymerized EDOT 单体准备 arachidic 酸(AA )/PEDOT 多层的磅电影。紫外力,英尺红外和 XPS 分析暗示 EDOT 是有效地在电影的 polymerized,并且因此,进行聚合物的 PEDOT 被生产。XRR 和 SIMS 的分析显示那部电影有安排得好的薄片结构,并且进一步的研究在破坏的 AA 电影显示出 EDOT 的那聚合原来的磅电影的整洁。这现象能与分层的结构上的聚合的破坏效果有关。我们使用了四点的探查和半导体仪器学习这部电影的传导性性质,并且观察到 AA/PEDOT 的传导性在有效传导网络与变化的处理时间拍摄有的突然的变化。那被“渗透”在进行多层的电影的隧道引起。测试结果也显示 AA/PEDOT 电影的传导性显然比纺纱涂层 PEDOT/PSS 电影的好或 ODA-SA/PEDOT-PSS 拍摄,它由于 PEDOT 结构的更高的结构并且订了电影结构。

英文摘要:

Adopting LB film method, an arachidic acid (AA)/PEDOT multilayer LB film was chosen, and polymerized EDOT monomers in hydrophilic group of LB to prepare arachidic acid (AA)/PEDOT multilayer LB film. UV-Vis, FT-IR and XPS analyses implied that EDOT was effectively polymerized in film, and thus PEDOT conducting polymer was produced. Analyses of XRR and SIMS indicated that film had a well-arranged lamella structure, and further research showed that polymerization of EDOT in AA film destroyed the orderliness of the original LB film. This phenomenon could be related to the destructive effect of polymerization on layered structure. We used four-point probe and semiconductor instrument to study the conductivity property of the film, and observed that the conductivity of AA/PEDOT film had sudden changes with the processing time of changes in effective conduction network. That was caused by "permeability" in conducting channel of multilayer film. The test results also indicated that the conductivity of AA/PEDOT film was obviously better than that of spin-coating PEDOT/PSS film or that of ODA-SA/PEDOT-PSS film, which was due to the higher π structure of PEDOT structure and ordered film structure.
