采用修饰Langmuir-Blodget(LB)膜法以二十烷酸(AA)LB膜为模板,通过3,4-乙烯二氧噻吩(EDOT)单体在LB膜亲水基团间聚合,制备了AA/PEDOT复合LB膜.实验分析表明薄膜具有较好的层状有序结构,并进一步研究发现EDOT在AA多层膜中的聚合破坏了原有LB膜的有序性,这与聚合过程对层状结构产生的破坏作用有关;研究了薄膜导电性能,发现AA/PEDOT多层膜的电导率随处理时间的变化产生突变,这与多层膜中导电通道的“渝渗”有关,在有效导电网络连通后电导率发生了突变.测试结果还表明AA/PEDOT膜导电性明显优于PEDOT旋涂膜和十八胺-硬脂酸/聚(3,4)乙烯二氧噻吩-聚苯乙烯磺(ODA-SA/PEDOT-PSS)复合膜.
The modified Langmuir-Blodget (LB) membrane was used to polymerize 3,4-ethylenedioxythiophene (EDOT) monomer onto the hydrophilic membrane of LB membrane by using eicosanoic acid (LB) / PEDOT composite LB film.Experimental analysis showed that the film has a good layered ordered structure, and further study found EDOT in the AA multilayer film undermines the original order LB film, which is the polymerization process of layer The structure of AA / PEDOT multilayers was studied. The conductivity of AA / PEDOT multilayers was found to be abruptly changed with the processing time, which was related to the " The results show that the electrical conductivity of AA / PEDOT film is obviously better than that of PEDOT spin-coating film and octadecylamine-stearic acid / poly (3,4) ethylenedioxythiophene-polybenzene Ethylene sulfonate (ODA-SA / PEDOT-PSS) composite membrane.
