通过共混法将不同浓度的聚乙二醇(PEG)加入聚二氧乙基噻吩/聚对苯乙烯磺酸(PEDOT-PSS)中制备了PEDOT-PSS/PEG复合膜。采用四探针法测量复合膜的电导率。实验结果表明聚乙二醇的加入明显影响PEDOT-PSS的电导率。随着聚乙二醇浓度的增加,复合膜的电导率迅速增加至最大值,然后缓慢下降。而且,聚乙二醇分子量和环境温度对复合膜的电导率也影响很大。在lnσ_(DC)和T~(-1/2)之间存在一个良好的线性关系。
PEDOT-PSS / PEG composite membranes were prepared by blending different concentrations of polyethylene glycol (PEG) into polydioxyethylthiophene / poly (p-styrenesulfonic acid) (PEDOT-PSS) The conductivity of the composite membrane was measured by four probe method. The experimental results show that the addition of polyethylene glycol significantly affects the conductivity of PEDOT-PSS. With the increase of polyethylene glycol concentration, the conductivity of the composite membrane rapidly increased to the maximum, and then decreased slowly. Moreover, the molecular weight of polyethylene glycol and the ambient temperature of the composite membrane conductivity also has a great influence. There is a good linear relationship between lnσ_ (DC) and T ~ (-1/2).
