Abstract: Two block SPEEK/PES copolymers were prepared via the postsulfonation reaction of the well designed precursors. The influence of microstructure/sequence distribution on the properties of the membranes was investigated. The block copolymers always had higher water uptake and proton conductivity in comparison with their random analogue. At 80 oC, the proton conductivities of the block copolymers were above 0.2 S/cm. The membranes of the block polymers exhibited obvious phase-separation microstructure. The study suggested that some properties could be improved by rational designing of the chemical architecture.
