The dual-network structure consists of a permanently cross-linkednetwork for structural stability and a reversibly cross-linked networkfor shape fixation and recovery.

Subsequently, by extending the entropy compensationtheory, the dissociation probability of the reversibly cross-linkednetwork upon cooling is well characterized.
