导电聚合物可以通过芳族单体在电极表面上的电化学氧化以膜状态容易地获得。为了通过电聚合制备导电聚合物纤维，在常规方法中，模板如多孔膜是必需的。在这里，我们报道了通过交流（AC）双极电解进行3，4-乙烯二氧噻吩及其衍生物的电聚合。聚（3，4-乙撑二氧噻吩）（PEDOT）衍生物被发现传播作为纤维的形式，从末端的Au线用作双极电极（BPE）平行于外部电场，而不使用模板。施加的频率和溶剂上的形态，这些PEDOT纤维的生长速率和支化度的影响进行了研究。此外，还论证了导电材料网络形成的链增长模型。 芳香族单体在双极电极上的电聚合是一种很有前途的导电物体表面改性方法。在这里，作者发现一些导电聚合物作为纤维传播，开辟了通过无线过程生长导电聚合物网络的可能性。
Conducting polymers can be easily obtained by electrochemical oxidation of aromatic monomers on an electrode surface as a film state. To prepare conducting polymer fibres by electropolymerization, templates such as porous membranes are necessary in the conventional methods. Here we report the electropolymerization of 3,4-ethylenedioxythiophene and its derivatives by alternating current (AC)-bipolar electrolysis. Poly(3,4-ethylenedioxythiophene) (PEDOT) derivatives were found to propagate as a fibre form from the ends of Au wires used as bipolar electrodes (BPEs) parallel to an external electric field, without the use of templates. The effects of applied frequency and of the solvent on the morphology, growth rate and degree of branching of these PEDOT fibres were investigated. In addition, a chain-growth model for the formation of conductive material networks was also demonstrated. Electropolymerization of aromatic monomers on bipolar electrodes is emerging as promising route to the surface modification of conductive objects. Here, the authors discover that some conducting polymers propagate as fibres, opening up the possibility of growing conductive polymer networks via a wireless process.
