This study presents a novel method to convert traditional elastomers into tough hydrogels using radiation-induced penetrating polymerization. The resulting hydrogel combines the properties of both elastomers and hydrogels, offering a comprehensive set of mechanical and biological properties similar to human skin. The hydrogel is composed of a hydrophobic crosslinking network from elastomers and grafted hydrophilic chains, which act as elastic collagen fibers and water-rich substances. This hybrid material exhibits excellent Young's modulus, friction coefficients, and compression and puncture load capacities, making it a promising candidate for artificial skin, fluid flow control, and wound dressing applications. The method is versatile and can be applied to various elastomers, including silicone rubber, natural latex, and polyurethane. The hydrogel's responsiveness to ions and shape adaptability further enhance its potential in bionic devices and biomedical engineering.This study presents a novel method to convert traditional elastomers into tough hydrogels using radiation-induced penetrating polymerization.
