1. A method for preparing a fluorine- and chlorine-containing conductive polymer resin, comprising:

  • adding, to a reaction vessel, 1%-20% by weight of a fluorine-containing sulfonyl fluoride liquid phase monomer which is capable of free radical polymerization, 79%-98% by weight of purified water, and 0.01%-1% by weight of a fluorine-containing surfactant, and stirring the mixture at a high speed to give a prepolymer emulsion;

    introducing, into the reaction vessel, a gaseous monomer mixture of one or both of tetrafluoroethylene and vinylidene fluoride and chlorotrifluoroethylene under a reaction pressure of 5 kg or more, introducing a radical initiator, and allowing the reaction to proceed at a temperature of 20-120°

    C., under a reaction pressure of 5-25 kg, for 15-180 min to give the reaction product which is an emulsion of a fluorine- and chlorine-containing sulfonyl fluoride polymer, wherein the fluorine-containing sulfonyl fluoride liquid phase monomer and the gaseous monomer mixture that actually participate in the radical polymerization are at a ratio ranging from 1;

    3 to 3;

    1 by weight, and the radical initiator added to the reaction vessel and the fluorine-containing sulfonyl fluoride liquid phase monomer are at a ratio ranging from 0.01% to 3.0% by weight; and

    hydrolyzing the emulsion of the fluorine- and chlorine-containing sulfonyl fluoride polymer, and then condensing, washing and drying the hydrolysate to give a fluorine- and chlorine-containing conductive polymer resin.
