Abstract:
 The full interpenetrating network anion exchange membranes were prepared based on quaternized- chitosan (QCS) and cellulose (CM) as materials and glutaraldehyde(GA) as crosslinkers. Thermal stabiit, water uptake, swelling ratio, mechanical properties, electrical conductivity and ion exchange capacity were all investigated in this research. The results show that the anionic conductivity, flexibility and mechanical property are highly improved by incorporating CM. No apparent decrease in anionic conductivity、water uptake and tensile stress was observed for the membranes after immersed in 10 mol•L-1 KOH (60℃) for 240 h. On the contrary, the anionic conductivity was increased from 3.43×10-2 S•cm-1 (0 h) to 4.60×10-2 S•cm-1 (240 h) and 8.73×10-2 S•cm-1(0h) to 1.009×10-1S•cm-1(240h) , which were measured at 30oC and 70oC. The results , indicating that the membranes with good alkaline resistance stability are promising for potential use in alkaline direct methanol fuel cells.
