Carbon cloth with brush-like polyaniline (BL-PANI) nanowire arrays generated on the surface was utilized as anode material in this study to improve the power output of MFCs. A novel pulsed voltage method was applied to fabricate BL-PANI with PANI nanowires of ∼230nm of length. By using BL-PANI modified carbon cloth as anode, the power output was improved by 58.1% and 36.1% compared to that of plain carbon cloth and PANI modified carbon cloth with ordinary structure, respectively. Electrochemical tests revealed that both electron transfer resistance and charge transfer resistance were decreased owing to high specific area for microbes' growth and diffusion of charged species.
本研究利用表面生成刷状聚苯胺（BL-PANI）纳米线阵列的碳纤维布作为阳极材料，以提高 MFC 的功率输出。采用一种新颖的脉冲电压法制备了长度约为 230nm 的 PANI 纳米线的 BL-PANI。使用 BL-PANI 修饰的碳纤维布作为阳极，与普通结构的普通碳纤维布和 PANI 修饰的碳纤维布相比，功率输出分别提高了 58.1%和 36.1%。电化学测试表明，由于微生物生长和带电物质扩散的高比表面积，电子转移电阻和电荷转移电阻都降低了。
