Fig.2 Schematic diagram of chemical reaction process of porous sulfonated SEBS fiber membrane. (a) Hydrolyzation of FDA to form a methylene carbocation; (b) Formation of a methylene bridge bond by aromatic ring with carbocation via Friedel-Crafts alkylation; (c) Chloroethyl cation reacts with benzene rings of SFBS to introduce chloroethyl group;(d) Introduction of sulfonic acid group via an electrophilic substitution reaction
