Abstract
The present technology relates to a polymeric material including a plurality of polymer subunits and an active cross-linker, wherein the active cross-linker is covalently linked to the plurality of polymer subunits. The active cross-linker offers a key building block for constructing novel molecular architecture in chemomechanical soft materials and illustrates a new approach to tailor material properties.
