In this work, high strength conductive hydrogels intensified with intermolecular hydrogen bonding are fabricated by in situ mixing poly（2-vinyl-4,6-diamino-1,3,5-triazine-co-polyethylene glycol diacrylates）（PVDT-PEGDA） hydrogels with poly（3,4-ethylenedioxythiophene）-poly（styrenesulfonate）（PEDOT/PSS）. The conductive hydrogels in deionized water exhibit high mechanical performances with compressive strength and tensile strength in the range of 7.58-9.52 MPa and 0.48-1.20 MPa respectively, which are ascribed to the intermolecular hydrogen bonding interactions of diaminotriazinediaminotriazine（DAT-DAT） in the network. Meanwhile, adding PEDOT/PSS can significantly increase both the specific conductivities and equilibrium water contents of the hydrogels. These cytocompatible conductive hydrogels may have a great potential to be used as electrical stimuli responsive soft biomaterials.展开更多
