COMPOSITE HAVING ION EXCHANGE FUNCTION AND PREPARATION METHOD AND USE THEREOF

摘要

A composite having ion exchange function, preparation method and use thereof are provided. The composite is formed by compounding ion exchange resin with fluorine-contained polymer porous membrane, wherein the nitrile groups in the ion exchange resin react with the nitrile groups grafted on the fluorine-contained polymer porous membrane to form triazine ring crosslinked structure. The composite has excellent mechanical property and gas impermeability, high ion exchange capacity and high electroconductivity.
