The preparation of soluble conducting polymers proceeds by the chemical oxidation method in the presence of water‐soluble polyelectrolytes. Among conducting polymers, polyethylene‐(3,4‐dioxythiophene) (PEDOT) is the most investigated due to its intrinsic properties. In this work, for the first time a simple method of ethylene‐(3,4‐dioxythiophne) self‐polymerization without applying any oxidant and with the formation of PEDOT solution at room temperature with a yield of 100% is presented. This PEDOT solution could be deposited on many desirable surfaces (by simple evaporation of the solvent) for various applications from photovoltaic cell to pseudocapacitors. Moreover, it is discovered that the self‐polymerization method does not produce byproducts, which makes the method environmentally friendly. The effect of light and different acids is explored. Fourier transform infrared spectroscopy, X‐ray photoelectron spectroscopy (XPS), and Raman spectroscopy confirm the formation of PEDOT by the self‐polymerization method. Moreover, this method provides a way to obtain and study individual PEDOT chains. The self‐polymerization method may be applied for the preparation of other conducting polymers.

可溶性PEDOT的制备方法：室温下无氧化剂的EDOT自聚合

在水溶性聚电解质存在下，通过化学氧化方法进行可溶性导电聚合物的制备。在导电聚合物中，聚乙烯-（3,4-二氧噻吩）（PEDOT）由于其固有特性而受到最多的研究。在这项工作中，首次提出了一种简单的乙烯-（3,4-二氧噻吩）自聚合方法，无需施加任何氧化剂，并且在室温下形成PEDOT溶液，产率为100％。可以将该PEDOT溶液沉积在许多所需的表面上（通过简单地蒸发溶剂），以用于从光伏电池到伪电容器的各种应用。此外，发现自聚合方法不会产生副产物，这使该方法对环境友好。探索了光和不同酸的影响。傅里叶变换红外光谱，X射线光电子能谱（XPS）和拉曼光谱证实了通过自聚合方法形成的PEDOT。此外，此方法提供了一种获取和研究单个PEDOT链的方法。自聚合方法可用于制备其他导电聚合物。
