First Claim
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.

Abstract
Disclosed are a method for a preparing fluorine- and chlorine-containing conductive polymer resin, a single-side or double-side filled composite film prepared using the fluorine- and chlorine-containing conductive polymer resin, and a method for preparing the film. The fluorine- and chlorine-containing conductive polymer single-side or double-side filled composite film comprises a microporous film skeleton and the fluorine- and a chlorine-containing conductive polymer resin. The composite film is mechanically stronger, more waterproof, more impervious to water and toxic and harmful chemicals, and more moisture permeability. When applied to biochemical protective clothing, it can greatly enhance the combat effectiveness of the soldiers because it is light and more impervious to water and toxic and harmful chemicals, brings about comfort, and keeps the soldiers warm. When applied to fuel cells, it can provide better electrical properties due to its high conductivity and can allow the fuel, such as hydrogen or alcohol, to burn more completely.
