Abstract: This study aims to design a novel composite polymer membrane to enhance Microbial Fuel Cell (MFC) performance. For this purpose, composite polymer membranes were synthesized by incorporating the Graphene oxide/Chitosan/2-aminothiazole/SO3H (GO-CS-2-aminothiazole-SO3H) in the sulfonated polyethersulfone (SPES) for electricity generation and wastewater treatment. The fabricated composite membranes (SPES/GO-CS-2-aminothiazole-SO3H) were analyzed using various methods. By embedding secondary amine (R'R″NH) and sulfonic acid (-SO3H) groups into the membranes, MFC performance, and membrane selectivity were ameliorated. A comparably remarkable power density (76.77 mW m−2) was obtained by utilizing the SPES/GO-CS-2-aminothiazole-SO3H 0.1 wt% as the membrane in double-chamber MFC, significantly higher than the result obtained for the SPES (3.19 mW m−2) and SPES/GO-CS 0.1 wt% (22.67 mW m−2) membranes. With the composite membrane, SPES/GO-CS-2-aminothiazole-SO3H 0.1 wt% in MFC, the COD removal efficiency of 89.54 % and a coulombic efficiency of 84.18 % were achieved. The results reveal that SPES/GO-CS-2-aminothiazole-SO3H 0.1 % can be considered a favorable membrane for MFC application.
