The integration of biological building-blocks with synthetic nanomaterials may permit unprecedented ability to detect, disinfect and completely remove pathogens in water. We hereby described the synthesis of biodegradable, interpenetrating polymeric networks of poly(amic) acid (PAA), glutaraldehde-derivatized PAA(PAA-GA) andchitosan-modified poly(amic)acid (PAA-CS) usingp hase-inversion procedures.The characterization data from NMR,FT-IR, SEM and cyclic voltammetry confirmed the successful formation of electroactive, bifunctional, glutaraldehyde-linked PAA membranes. Toxicological, electrochemical and mechanical characterization data showed the successful formation of non-toxic,biodegradable, porous,free-standing and mechanically strong membranes.PAA-GA showed the highest modulus of 5 68.1Mpa followedby PAA-CS-GA (495.0Mpa).The optimized membranes we retested against three of the most common drinking watercontaminants, namely Escherichiacoli,Citrobacter freundii and Staphylococcusepidermidis with 100% removalachievedusingdeadend filtration and tangential flow filtration.
