Abstract
The invention provides highly resilient synthetic hydrogels, which can be prepared, for example, by using the efficient thiol-norbornene chemistry to cross-link hydrophilic poly(ethylene glycol) (PEG) and hydrophobic polydimethylsiloxane (PDMS) polymer chains. The simple hydrogel system with enhanced mechanical properties is useful in many applications, including in the biomedical field and in the design of protective and corrective wear.
