Claim:
1. A method of manufacturing a polymer of fluorine-containing sulfonated poly(arylene ether)s, comprising steps of: (S01) providing a fluorine-containing monomer having a structure given in the following formula (I): wherein X is D1 is halogen or hydroxyl group; and Z is independently selected from fluoro- or trifluoromethyl group; (S02) providing a multi-phenyl monomer having a structure given in the following formula (II): wherein Y is and D2 is halogen or hydroxyl group; (S03) processing a nucleophilic polycondensation between the fluorine-containing monomer and the multi-phenyl monomer to form a polymer of fluorine-containing poly(arylene ether)s having a structure given in the following formula (III): wherein n is an integer greater than or equal to 2; and D2 is the hydroxyl group if D1 is the halogen group, or D2 is the halogen group if D1 is the hydroxyl group; and (S04) carrying out a sulfonation modification of the polymer of fluorine-containing poly(arylene ether)s to form a polymer of fluorine-containing sulfonated poly(arylene ether)s having a molecular formula given in the following formula (1): wherein j is an integer from 1 to 10.
