| Research Abstract |
To develop a polymer electrolyte membrane with high proton conductivity in the thickness direction of the membrane, a ETFE film was first irradiated with swift heavy ions to form the cylindrical damage zone (the so-called latent track region), followed by UV-grafting of styrene into the latent tracks and subsequent sulfonation. The UV-grafting was found to occur only in the latent tracks. As a result, the proton conductivity of the resulted membrane was quite higher in the thickness direction than that in the surface direction.
