We present a novel approach to the fabrication of advanced polymeric nanocomposite hydrogels from polyacrylamide (PAAm) by incorporation of graphene‐silver‐polyethylenedioxythiophene‐polystyrene sulfonate (rGO‐Ag‐PEDOT/PSS) by photopolymerization method. Infrared spectroscopy was employed to characterize the structure of the hydrogels. The internal network structure of nanocomposite hydrogels was investigated by scanning electron microscope. Swelling, deswelling, and mechanical properties of the hydrogels were investigated. The compressive strength of nanocomposite hydrogels reaches maximum of 1.71 MPa when the ratio of rGO‐Ag‐PEDOT/PSS to PAAm was 0.3 wt%, which is 1.57 times higher than that of PAAm hydrogels (1.09 MPa). The electrical conductivity of the PAAm‐rGO‐Ag‐PEDOT/PSS hydrogel was found to be 3.91 × 10 −5 S cm −1 . Copyright © 2015 John Wiley & Sons, Ltd.
