摘要
The present invention provides a cation-exchange composite membrane comprising a copolymer containing a styrene repeating unit introduced with a sulfonation group, a tert-butylstyrene repeating unit and a crosslink repeating unit, an olefin additive, a plasticizer and a polyvinyl halide polymer. The cation-exchange composite membrane comprising a copolymer containing a styrene repeating unit introduced with a sulfonation group, a tert-butylstyrene repeating unit and a crosslink repeating unit, an olefin additive, a plasticizer and a polyvinyl halide polymer of the present invention not only displays low electrical resistance, excellent ion exchange capability, excellent ionic conductivity, excellent mechanical properties, excellent chemical properties, and processability, but also is easy to regulate its ion exchange ability and ionic conductivity. Also, the composite membrane of the invention is easier to produce and cheaper to manufacture than the conventional cation-exchange composite membrane.
