In order for hydrogels to be used in applications such as electro-driven actuators and artificial muscles, they must have good mechanical strength and also be electrically conductive. In this work, novel electro-conductive and mechanically-tough double network hydrogels (E-DN gels) are synthesized by polymerization of 3, 4-ethylenedioxythiophene in the presence of a double network hydrogel (DN gel) matrix. Poly(3, 4-ethylenedioxythiophene) incorporated into the DN gel matrix greatly improves not only electronic conductivity, but also mechanical properties, reinforcing the DN gel.
