Triboelectric generators (TEGs) are devices that convert mechanical energy to electrical energy through triboelectric charging of different material surfaces at periodic contact. Typically, such devices consist of two dielectric contacting layers with electrodes attached on the non-contacting sides but alternatively, one material can simultaneously serve as both a contacting and an electrode material. In this work, we report the use of poly(3,4-ethylenedioxythiophene) (PEDOT) for TEG device were PEDOT film serves as both a contacting surface to PDMS and as an electrode. Two different PEDOT films were prepared on glass substrates by vapour-phase polymerization (VPP) and VPP combined with electropolymerization method and compared as TEG electrodes. Additionally, PEDOT/poly(1,6-hexanediol-co-citric acid) (PHC) composite films were prepared by using solution casting polymerization. These methods yielded PEDOT films with different morphology, surface roughness and conductivity. Best performance was demonstrated for the PEDOT film with the lowest surface roughness (1.88 nm RMS), prepared by VPP method, which generated peak current of 0.45 mA/m² and power density of 95 W/m², outperforming Sn doped In₂O₃ electrode approximately by threefold in the same experimental setup.

摩擦发电机（TEG）是通过周期性接触不同材料表面的摩擦带电将机械能转换为电能的设备。典型地，这样的装置由两个电介质接触层组成，其中电极附接在非接触侧上，但是可替代地，一种材料可以同时用作接触材料和电极材料。在这项工作中，我们报道了聚（3,4-乙撑二氧噻吩）（PEDOT）用于TEG器件，其中PEDOT膜既用作PDMS的接触面又用作电极。采用气相聚合法（VPP）和电聚合法结合VPP在玻璃基板上制备了两种不同的PEDOT膜，并作为TEG电极进行了比较。另外，PEDOT /聚（1,6-己二醇-co柠檬酸（PHC）复合膜是采用溶液流延聚合法制备的。这些方法产生了具有不同形态，表面粗糙度和电导率的PEDOT膜。通过VPP方法制备的具有最低表面粗糙度（1.88 nm RMS）的PEDOT膜表现出最佳性能，该膜产生的峰值电流为0.45 mA / m ²，功率密度为95 W / m ²，优于掺杂Sn的In ₂ O在相同的实验设置中，大约3倍的_3个电极。
