Abstract: Hybrid anion exchange membranes of quaternized poly(vinyl alcohol) (QPVA) and hydroxyapatite(HA) were prepared and characterized by FT-IR (Fourier transform infrared spectroscopy) and TGA (thermogravimeteric analysis), respectively. Physical chemical properties of the hybrid membranes were investigated. The results indicated that the decomposition temperature of the hybrid membranes is increased about 30°C comparing with that of QPVA. The presence of HA in the hybrid membranes decreases the membrane swelling, improves the membrane strength, and alleviates the decrease in conductivity of the hybrid membrane due to the water evaporation at elevated temperatures. With the increasing of HA in the hybrid membrane from 0 to 75.0%, the volume swelling decreases from 105.5% to 55.5%, the tensile strength increases from 47.9 to 69.5MPa, and the IEC decreases from 0.72mmol/g to 0.54mmol/g, respectively.
