Physicochemical studies of chitosan blended sulfonated poly ether-ether ketone and graphene oxide as filler for direct methanol fuel cell
Chitosan (CS) was successfully extracted from the shrimp shell of Litopenaeus vanamei and used as a biopolymer for the fuel cells. The composite membranes containing chitosan blended poly ether-ether ketone (PEEK) and graphene oxide (GO) as filler were fabricated using the solvent evaporation method...
