摘要

•Ternary multisilicon copolymers containing –COOH and –SO3Na groups are prepared.•Membranes with controllable multi-functional groups are developed.•The membranes have high dialysis coefficients of NaOH (0.013–0.021m/h).•Coupling effects can be formed for the transport of both Na+ and OH− ions.
