A conductive, antibacterial, and antifouling hydrogel based on zwitterion

This paper proposes a cationic double‐network hydrogel, which has good electrical conductivity, antibacterial properties, antiprotein adsorption, and mechanical properties. The cationic polymer formed a conductive path in the hydrogel network, so that the gel had good conductivity. With the increase of carboxybetaine ester, the conductivity gradually increases. As a sensor, hydrogel could respond quickly to strains such as stretching and...
