Abstract In this work, we have successfully cross-linked the different weight ratio of Chitosan-PVA blend
with sulfuric acid. The effect of cross-linker on the properties of blends are studied by using
different experimental technique. The cross-linked membrane provides higher ion exchange
capacity due to the procurement of extra ionic hooping sites in the membrane. The compatibility
of the blends are confirmed from the FTIR and DSC analysis. The crosslinking reaction fastening
the phase transition behavior of the blends which reduces the glass transition temperature. The
highly compatiblized cross-linked blend provides higher tensile strength and lower modulus at
moderate temperature. The significant… More >
