Sulfonated Poly

Aldehyde terminated sulfonated poly (arylene ether sulfone) (SPAES-CHO) is prepared by a series of nucleophilic substitution reaction based on SPAES in this paper. Novel SPAES-graft-SPVA (SPAES-g-SPVA) membranes are fabricated by acetal reaction between SPAES-CHO and different amounts of sulfonated poly (vinyl alcohol) (SPVA). The 1H-NMR and FTIR indicate the successful preparation of SPAES-CHO and SPAES-g-SPVA membranes. With the introduction of SPVA, the SPAES-g-SPVA membranes have much lower methanol permeability than pure SPAES membrane and Nafion117 membrane. The methanol permeability coefficients of the SPAES-g-SPVA membranes decrease from 3.41 × 10−7 cm2 s−1 to 1.67 × 10−7 cm2 s−1 with the increase of SPVA content. And the proton conductivity of all the membranes is higher than 15 mS cm−1 at 25°C. Moreover, SPAES-g-SPVA membranes exhibit high proton selectivity. Especially, SPAES-g-SPVA-30% membrane has the highest proton selectivity, which is nearly five times higher than Nafion117.

Sulfonated Poly

A new series of hydrophobic-hydrophilic multiblock sulfonated poly (arylene ether ketone)-b-poly (arylene ether ketone) copolymers were successfully synthesized and evaluated for use as proton exchange membranes (PEMs). The membrane properties of block copolymers including ion exchange capacities (IECs), water uptake and proton conductivities were characterized for the multiblock copolymers and compared with random sulfonated poly (arylene ether) s and other multiblock copolymer membranes at similar ion exchange capacity value. This series of multiblock copolymers showed moderate conductivities up to 0.063 S/cm at 80 °C with very low water uptake of 19%. Therefore, they are considered to be promising PEM materials for fuel cells.
