A series of Poly(styrene-b-styrenesulfonic acid sodium salt)(PS-b-PSSNa) were synthesized via stable radical polymerization (SFRP) using TEMPO and the block copolymer were blended with poly(2,6-dimethyl -1,4-phenylene oxide) (PPO) to prepare fuel cell membranes. Block length ratio and total molecular weight of PS-b-PSSA were varied differently and weight ratio of PPO/PS-b-PSSA was also controlled. The blend membranes showed good ion conductivity, low methanol permeability, and good thermal property. |
