主权项

1. A shape-memory bicontinuous composite structure comprising a continuous polymeric porous solid matrix composed of a plurality of backbone chains and a continuous hydrogel filling the pores in said continuous polymeric porous solid matrix, wherein at least a portion of said backbone chains comprising a plurality of side-chain moieties, said plurality of backbone chains is arranged such that said plurality of side-chain moieties is capable of forming a crystalline structure, and wherein at least a portion of said backbone chains are crosslinked substantially at a matrix-hydrogel interface of the structure.
