UV radiation-induced photografting of styrene into ETFE films for the preparation of fuel cell membranes was carried out. The proton conductivity in thickness direction of membranes prepared by the vapor- and liquid-phase photografting can reach as high as 0.036 and 0.072 S/cm, respectively. The higher conductivity in the liquid-phase grafting is close to the homogeneity of graft chain distribution in the membrane.
