The invention provides a pure PEDOT: PSS hydrogel rapidly induced by a surfactant and a preparation method thereof, a PEDOT: PSS aqueous solution containing a hydrophobic core of PEDOT and a hydrophilic outer micelle shell of PSS is used as a matrix, the matrix is fully stirred and uniformly mixed through a cationic surfactant, the mixture is poured in a mold or a substrate after being uniformly mixed, annealing recrystallization is performed after drying, and the pure PEDOT: PSS hydrogel rapidly induced by the surfactant is obtained. In the annealing process, mechanical constraint in the plane direction is formed by utilizing the adhesion between the precursor solution and a mold or a substrate, an annealed xerogel film is obtained, then the xerogel film is expanded again to form hydrogel, and the pure PEDOT: PSS hydrogel is obtained by completely removing the cationic active agent residue; the hydrogel has high conductivity, high stretchability and low Young modulus, and has excellent ...

The invention provides a patterned PEDOT: PSS hydrogel based on electrochemical pulse deposition and a preparation method of the patterned PEDOT: PSS hydrogel. The preparation device comprises an electrolytic tank, an electrochemical work station, a substrate, a conductive layer and a sacrificial metal layer, a PEDOT: PSS aqueous solution is arranged in the electrolytic tank, the conductive layer is connected with a working electrode of the electrochemical work station, the sacrificial metal layer forms metal cations under excitation of the electrochemical work station, the metal cations realize electrostatic adsorption on PEDOT: PSS in the PEDOT: PSS aqueous solution, and the sacrificial metal layer is formed. And finally, a patterned shape taking the sacrificial metal layer as a template is formed on the conductive layer. According to the method, the thickness of the patterned PEDOT: PSS hydrogel is regulated and controlled by regulating and controlling various deposition parameters.
