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
