Abstract:Smart hydrogel materials have demonstrated significant advantages in application fields, such as drug delivery, tissue engineering, and smart sensing. However, developing a stimuli-responsive hydrogel that is simple to prepare, programmable, and capable of rapid response remains a challenge. Herein, we employed a polyvinyl alcohol (PVA) polymer film to hydrolyze and diffuse in a hydrogel monomer precursor solution, thereby constructing a diffusion layer and preparing an anisotropic hydrogel with a multiphase g… 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.
