The hemicellulose hydrogel was used as the matrix to adsorb pyrrole monomer which undergoes in situ polymerization by chemical oxidation to form polypyrrole to produce the composite hydrogel with conductive properties. The chemical structure and microstructure were characterized and observed by using Fourier transform infrared spectroscopy, scanning electron microscope. The rheological properties under low shear frequency were measured by the rotary rheometer. The electrical properties were tested by four-probe tester and electrochemical workstation. It was found that the polypyrrole was successfully combined with hemicellulose hydrogel, and the resulting conductive hydrogel had a stable macroporous structure with strong water absorption capacity, with equilibrium swelling degree up to 420%. The prepared hydrogel shows high elasticity, exhibiting typical solid nature properties and certain pseudoplastic fluid properties. In addition, the composite hydrogels display good electrical properties. Its direct current conductivity reached 5.6×10^-3 S/cm, and the alternating current impedance had obvious frequency dependence.
