A BETA-CYCLODEXTRIN DERIVATIVE AND POLYELECTROLYTE MULTILAYER COMPRISING BETA-CYCLODEXTRIN DERIVATIVE LAYER

摘要

PURPOSE: A beta-cyclodextrin derivative and a polymer electrolyte multi-layered membrane containing thereof are provided to maintain the property of beta-cyclodextrin, and to offer various functions to the multi-layered membrane. CONSTITUTION: A beta-cyclodextrin derivative is obtained by reacting beta-cyclodextrin, epichlorohydrin, and choline chloride. A polymer contains the beta-cyclodextrin derivative as a monomer. A polymer electrolyte multi-layered membrane includes an anionic polymer electrolyte layer and a cationic polymer electrolyte layer. An outermost layer of one of the layers formed with either the beta-cyclodextrin derivative or the polymer including the beta-cyclodextrin derivative.
