An organic species bearing an organic sulfonic acid (HSO3-) was grafted onto the surface of Titanium oxide (TiO2) bysulfuric acid and the composite membranes were cast together with sulfonated chitosan and PEO. The performance of the schitosan/PEO/s-TiO2 composite membranes for microbial fuel cells (MFCs) was evaluated in terms of proton conductivity, oxidativestability and Ion Exchange Capacity (IEC).The IEC, proton conductivity of the composite membrane increased dramatically withincreasing contentof s-TiO2in the composite membrane. The combination of these effects led to a significantimprovement in theperformance of MFCs made with s-chitosan/PEO/s-TiO2 composite membranes. All the prepared s-chitosan/PEO/s-TiO2nanocomposite membranes exhibit better stability against oxidativedegradation, water uptake and retention ability protonconductivity. The membranes were investigated by FTIR, XRD. Thus, through chemical modifications the physico-chemical propertiesof naturalabundant biopolymer chitosan can be enhanced for its use as an environmentally sustainable PEM in MFC technology.
