Abstract: PURPOSE: An anion-exchange composite membrane is provided to ensure low electric resistance, and excellent ion-exchange capacity, mechanical property, chemical property and processability, and to facilitate ion-exchange capacity and ion conductivity by controlling the composition of a styrene-based monomer and vinylbenzyl-based monomer. CONSTITUTION: A method for preparing an anion-exchange composite membrane comprises the steps of: impregnating a porous film in a polymerization solution including a styrene-based monomer, vinyl benzene-based monomer, crosslinking agent and initiator; polymerizing the impregnated porous film to prepare a styrene-vinyl benzene-based copolymer composite film; and reacting tertiary amine with the styrene-vinyl benzene-based copolymer and then introducing quaternary ammonium group as a negative ion exchanger.
