Dextrin-DADMAC based double network polymer gel electrolyte, method for preparing the same and energy storage device including the same

Abstract

A dextrin-DADMAC based double network polymer gel electrolyte is disclosed. The gel electrolyte includes: a first polymer network having a network structure in which linear main chains including diallyldimethylammonium chloride (DADMAC) monomers are crosslinked with each other via N,N-methylenebisacrylamide; a second polymer network including a dextrin polymer chain, and entangled with the first polymer network to form a double network composed of the first and second polymer networks; and a liquid electrolyte supported inside the double network composed of the first and second polymer networks. In addition, mechanical properties of the polymer gel electrolyte are improved via an ion exchange reaction between the polymer gel electrolyte and a salt.
