Abstract:
1. A method for preparing anion exchange composite membrane filled with crosslinked polymer electrolytes, the method comprising: (A) preparing anion exchange electrolyte precursor solution, said anion exchange electrolyte precursor solution consisting of a electrolyte monomer of tetravalent ammonium salt having a cation, a bisacrylamide crosslinker having tertiary amine functional group, an initiator and water; (B) impregnating a porous polymer supporter into said electrolyte precursor solution; (C) forming a primary anion exchange membrane filled with crosslinked polymer electrolytes micropore by laminating said polymer supporter and crosslinking within a film; (D) deriving quanternary ammonium of said crosslinker having tertiary amine functional group by immersing said primary anion exchange membrane filled with crosslinked polymer electrolytes micropore in Vinylbenzyl chloride monomer solution; and (E) after said ammonium deriving is completed, preparing composite membrane filled with crosslinked polymer electrolytes by crosslinking, said crosslinking being radical polymerizing vinyl group of said electrolyte micropore filling membrane.
