Abstract: β-cyclodextrin (β-CD) was introduced into a mixed casting solution using polyvinyl alcohol
(PVA) and quaternized chitosan (QCS) as film matrix, and then these three substances were crosslinked in
the presence of a combined crosslinking agent of glutaraldehyde(GA) and melamine(MA) to preparea series
of host-guest complex (CD X-QCS Y-PVA Y, X is the mass fraction of β-CD, Y is the mass fraction of QCS and

PVA) OH conductive membranes based on cyclodextrin molecules with full interpenetrating network
structure. The results showed that when the mass fraction of β-CD increased, the content of hydroxyl group

and the amount of OH adsorption by complexing Ca increased, the ion exchange capacity (IEC), the
conductivity and the tensile strength all showed an increasing trend. However the water uptake, swelling
ratio and elongation at break decreased. When the dosage of β-CD was 20%(basd on the total mass of
β-CD、QCS and PVA, the same below), the conductive membrane exhibited the best comprehensive
performance. The water uptake and swelling ratio were 71.1% and 63.7%, respectively. The tensile strength
and elongation at break were 69.5% and 48.5%, respectively. And the ion exchange capacity was 2.64

mmol/g, the conductivity reached 7.1×10 S/cm at 70 ℃. The conductivity of the above membrane was
only decreased 17% after soaking for 240 h in 6 mol/L KOH solution at 70 ℃, indicating that the
membrane had good alkali stability.
