In order to further understand the influence of the polymer microstructure on proton conductivity of the membrane, a series of high molecular weight PVDF-g-SPS graft copolymers with similar EC 2.20 mmol/g and different graft densities (0.8, 1.4, 1.7, and 2.4 mol%) are compared in Figure 12.10. The major difference between these polymers is their microstructures, and therefore different morphologies are... [Pg.307]
