Smart hydrogels are considered as close mimics to the functions of biological entities. However, stimuli-responsive performance is often limited by slow diffusion process during water exchange with surrounding environment. Here, a homogenous hydrogel composed water-soluble spiropyran covalently attached polyacrylic acid network reported. This demonstrates rapid and reversible shape-morphing behavior in air, underwater, or oil. The mechanism involves protonation triggered light stimuli. release/capture protons regulates local proton concentration near carboxyl groups network, distinguishing it from existing stimuli-responsiveness based on bulk diffusion. environment-independent unique in-situ stimuli transfer process, resulting amongst parts single piece attributed. Eventually, light-controlled actuation demonstrated, offering exciting possibilities for applications flexible electronics, soft actuators/robots.
