Abstract:Ionic conductive hydrogels have emerged as promising candidates for wearable sensors. However, it is still challenging to fabricate hydrogels simultaneously with a balanced mechanical strength, ionic conductivity, and sensitivity. In this work, Poly(vinyl alcohol) (PVA)/Pullulan/Sodium chloride (NaCl) ionic conductive hydrogels were prepared by soaking frozen−thawed PVA/Pullulan hydrogels in NaCl solution to obtain the balanced properties. Due to the synergy of the semiinterpenetrating network and salting-out … Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
