- W2995202225 abstract "Chitosan-based membranes are among the most effective and efficient PEMs for fuel cells, however their low proton conductivity needs to be improved. In this study, chitosan, chloroacetate chitosan (CCS), chitosan blend with epoxidized natural rubber (ENR), and CCS with ENR blend based membranes were prepared by solution casting, crosslinked with NaOH and H2SO4, and investigated for physical, chemical, electrical and ionic properties. The functional groups were identified by ATR-FTIR spectroscopy and the peaks matched improved membrane properties. The surface roughness of the membranes was determined by AFM, and it increased with the amount of ENR. The electrical properties measured with an LCR meter showed that the CCS, CS and CS-B had the highest conductance, conductivity, capacitance and dielectric constant, while the CCS10/ENR8, CS10/ENR8 and CS15/ENR3 showed the highest resistance and resistivity. Furthermore, the CCS gave the lowest dissipation factor, which indicates its suitability for use in a PEM. In addition, the contact angle was relatively high for CS-B, CS and CCS." @default.
