Abstract: A preparation method of composite materials having ion exchange function is provided. The method comprises the following steps: adding a trace of strong protonic acid and/or Lewis acid as a catalyst into the material during compounding, to allow nitrile groups of at least one nitrile group-containing ion exchange resin and nitrile groups of functional monomers grafted on the porous fluoropolymer membrane to form a triazine ring crosslinked structure.
