Abstract

The invention relates to a method for preparing antistatic aqueous solution by the chemical oxypolymerization of 3, 4-ethylenedioxythiophene (EDOT), i.e., potassium peroxydisulfate is used as oxidizer, sodium polystyrene sulfonate aqueous solution is polymerized with the 3, 4-ethylenedioxythiophene and the antistatic aqueous solution with eminent performance is prepared after the most suitable proportion of all the monomers is determined. Being used as a coat, the antistatic aqueous solution prepared by adopting the method of the invention has low surface resistance (1*10<5>Omega / cm<2>), high mechanical strength, high visible light transmittance, and superior electrochemistry performance and thermal stability. The method is simple in operation and has low requirement on equipment.

Description

technical field [0001] The invention relates to a method for preparing an antistatic aqueous solution, in particular to a method for preparing an antistatic aqueous solution by chemical oxidation polymerization of thiophene monomers, that is, chemical oxidation polymerization of 3,4-ethylenedioxythiophene (EDOT). Background technique [0002] Since the discovery of conductive polymers in 1977, countries around the world have set off an upsurge of research on conductive polymers. A large number of studies have shown that various conjugated polymers can become conductive polymers with different conductive properties after doping. Representative conjugated polymers include polythiophene, polypyrrole, polyaniline, and polyparaphenylene. [0003] In the second half of the 1980s, Bayer Corporation of Germany successfully developed a new generation of conductive plastic 3,4-ethylenedioxythiophene (EDOT). It has the following outstanding properties: (1) high electrical conductivit...
