Abstract
A method for preparing a hydrogel includes forming a pre-gel comprising polymer and metal salt particles, unidirectionally-shrinking and dehydrating the pre-gel, and impregnating the unidirectionally shrunk and dehydrated pre-gel with an ion solution to crosslink and rehydrate the unidirectionally shrunk and dehydrated pre-gel to produce the hydrogel.
