PEDOT was synthesized by chemical polymerisation and characterised for its electrochemical insights. Three different anode configuration, namely graphite plate (GP), carbon cloth (CC) and graphite felt (GF) were then loaded with a fixed amount of PEDOT (2.5 mg/m(2)) denoted as GP-P, CC-P and GF-P respectively. The PEDOT coating improved the electrochemical characteristics and electron transfer capabilities of the anodes. They also contributed for enhanced MFC performances with maximum energy generation along with coulombic efficiency than the unmodified anodes. The morphological characteristics like higher surface area and open structure of felt material promoted both microbial formation and electrochemical active area. A maximum current density of 3.5A/m(2) was achieved for GF-P with CE and COD of 51% and 86% respectively. Thus, the GF-P anode excelled among the studied anodes with synergetic effect of PEDOT coating and structural configuration, making it as a potential optimum anode for MFC application.
PEDOT 通过化学聚合合成，并对其电化学特性进行了表征。然后，将三种不同的阳极结构，即石墨板（GP）、碳纤维布（CC）和石墨毡（GF），分别用固定量的 PEDOT（2.5mg/m(2)）负载，分别表示为 GP-P、CC-P 和 GF-P。PEDOT 涂层改善了阳极的电化学特性和电子转移能力。它们还提高了 MFC 的性能，与未改性的阳极相比，最大能量生成和库仑效率都有所提高。毡材料的更高表面积和开放结构等形态特征促进了微生物的形成和电化学活性面积的增加。GF-P 的最大电流密度达到 3.5A/m(2)，CE 和 COD 分别为 51%和 86%。因此，GF-P 阳极在研究的阳极中表现出色，PEDOT 涂层和结构配置具有协同效应，使其成为 MFC 应用的潜在最佳阳极。
