Double network (DN) hydrogels as promising soft-and-tough materials intrinsically possess extraordinary mechanical strength and toughness due to their unique contrasting network structures, strong interpenetrating network entanglement, and efficient energy dissipation. It has been ~11 years since the first PAMPS/PAAm DN hydrogel was developed, but the research and development of new DN hydrogels are still at a very early stage. A vast number of network monomers available in current chemical inventory provide the possibility to design new DN gels and to explore a fundamental relationship of DN gels among network structures, mechanical properties, and toughening mechanisms, which help to derive new design principles for the next-generation tough hydrogels. In this review, we strive to highlight the development and fundamentals of DN gels covering from preparation methods, network structures, to toughening mechanisms over the last decade.
