英文摘要：

Conducting polymer hydrogels have been synthesized through a one-step procedure via the supramolecular self-assembly between polymers and multivalent cations.In a static condition,the gelation process happens simultaneously with the polymerization process with the multivalent cations acting as both the oxidant and the ionic crosslinker.As-prepared hydrogels,which are originally a semi-interpenetrating polymer network（semi-IPN） hydrogels,exhibit expanded-coil conformation in polymer chains,possess controllable microstructure and phase-separate at nanometer scale.The function of the static condition is analysed,and the gelation mechanism is studied.Such a supramolecular self-assembly method is proved to be versatile for the fabrication of conducting polymer hydrogels.Also the fabrication condition is modulated based on systematical researches,and PEDOT-PSS hydrogels with self-strengthening functions are prepared.The self-strengthening mechanism is demonstrated to be in close relationship with the microstructure and the phase structure of the materials.
