In this work, a fast, simple, low cost, atmospheric pressure based vapor phase polymerization (VPP) of 3, 4-ethylenedioxythiophene (EDOT) has been utilized with controlled substrate temperature. This technique enabled the production of highly electrically conducting thin films of poly (3, 4-ethylenedioxythiophene) (PEDOT). Well-ordered PEDOT films were produced at a nanometer scale by using layer-by-layer technique. Films showed conductance up to 3208 S/cm, and sheet resistance, 20.55 Ω/□ that is close to commercially available indium tin oxide (ITO) coated glasses. FTIR, Raman, and UV-Visible studies revealed a polymer in highly conducting form obtained by controlling the VPP method parameters. The surface morphology was studied by atomic force microscopy (AFM). Cyclic voltammetry (CV) and electrochemical impedance spectroscopy (EIS) measurements were carried out on PEDOT films without any current collector. The VPP PEDOT films have potential to be used in a variety of transparent electrode applications as well as in supercapacitors.

在这项工作中，已经在控制衬底温度的情况下使用了一种快速，简单，低成本，基于大气压的3,4-乙撑二氧噻吩（EDOT）气相聚合（VPP）。该技术使得能够生产高导电性的聚（3,4-乙撑二氧噻吩）（PEDOT）薄膜。通过使用逐层技术，在纳米级生产了有序的PEDOT膜。薄膜的电导率高达3208 S / cm，薄层电阻为20.55Ω/□，接近市售的氧化铟锡（ITO）涂层玻璃。FTIR，拉曼和紫外线可见研究表明，通过控制VPP方法参数可获得高导电形式的聚合物。通过原子力显微镜（AFM）研究了表面形态。在没有任何集电器的情况下，在PEDOT膜上进行了循环伏安法（CV）和电化学阻抗谱（EIS）测量。VPP PEDOT膜有潜力用于各种透明电极应用以及超级电容器中。
