导电聚合物水凝胶是一类独特的材料，具有水凝胶和有机导体的有利特征，由于其固有的多孔结构而具有优异的电化学性能。在此，我们报告了一个简单的和可扩展的方法，用于合成导电聚吡咯水凝胶/碳纳米管（CPHs/CNTs）使用植酸作为胶凝剂和掺杂剂，这种复合材料被用作双室微生物燃料电池（MFC）的阳极。该材料的高电催化活性显著降低了界面电荷转移电阻，促进了阳极表面的细胞外电子转移。该复合材料的三维多孔结构和亲水性增强了阳极表面生物膜的形成。CPHs/CNTs阳极将最大功率密度从871 ± 33 mW m−2增加到1898 ± 46 mW m−2，并在双室MFC中表现出高稳定性。这些结果表明，CPHs/CNTs复合材料的合成提供了一种有效的方法来提高MFC的发电量。
Conducting polymer hydrogels, a unique class of materials having the advantageous features of both hydrogels and organic conductors, possess excellent electrochemical properties due to their intrinsic porous structure. Herein, we report a facile and scalable method for synthesizing conductive polypyrrole hydrogels/carbon nanotubes (CPHs/CNTs) using phytic acid as both gelator and dopant, and this composite was used as an anode in a dual-chamber microbial fuel cell (MFC). The high electrocatalytic activity of this material significantly reduced the interfacial charge transfer resistance and facilitated the extracellular electron transfer on the anode surface. The three dimensional porous structure and hydrophilicity of this composite enhanced the biofilm formation on the anode surface. CPHs/CNTs anode increased the maximum power density from 871 ± 33 mW m−2 to 1898 ± 46 mW m−2 and exhibited high stability in the two-chambered MFC. These results demonstrated that the synthesis of the CPHs/CNTs composite offered an effective approach towards enhancing the power production in MFCs.
