DETAILED DESCRIPTION - Preparing conductive polymer anticorrosive coating for metal grounding grid, involves combining 90-100 pts. wt. purified graphene nanosheets and 6-10 pts. wt. sodium lactate-zirconium coupling agent, 245-256 pts. wt. deionized water, and 55-60 pts. wt. ethanol, mechanical stirring for 15-20 minutes, adding 0.3-0.4 pts. wt. BYK163 dispersant to uniformly mixed mixture, treating with ultrasonic for 30-40 minutes to obtain graphene nanosheets dispersions, transferring 10-15 pts. wt. the washed bacterial cellulose into the reaction kettle, adding 28-30 pts. wt. 1% HCl solution, stirring with a glass rod, placing the mixed system in a 70-80 degrees C constant temperature water bath for reaction 21-22 hours, repeatedly washing the sample with distilled water until the pH of the washing solution is 6.8-7.0 to obtain moisturized purified bacterial cellulose. The purified bacterial cellulose in a moist state is formulated into a cellulose suspension with a specified concentration, and placed in an ultrasonic cell pulverizer. The ultrasonic time is set to 10-20 minutes and the ultrasonic power is 40-80 Watt. The ultrasonic frequency is 20-28 kilohertz, and cellulose suspension is subjected to high-intensity ultrasonic splitting treatment under the condition of -5-0 degrees C in an ice water bath to obtain a cellulose nanofibril suspension. The 4.6-5 pts. wt. aniline, 80-100 pts. wt. 1.5-2.0mol/L sulfuric acid solution are added, and used a magnetic stirrer to stir vigorously until the solution is uniform to obtain the aniline solution. The 40-50 pts. wt. 5% cellulose nanofibril suspension and 10-11.4 pts. wt. ammonium persulfate are dissolved in 30-40 pts. wt. 0.5-1mol/L sulfuric acid solution to prepare oxidant solution, which is added to the aniline solution, reacted for 2 hours at room temperature, poured the resulting product into the solvent extractor, and washed with deionized water, acetone and 0.1M HCl suspension until colorless, and the bacterial cellulose coated polyaniline composite is obtained. The graphene nanosheet dispersion is uniformly mixed with the bacterial cellulose coated polyaniline composite obtained and dried at 45-50 degrees C to a constant weight to obtain graphene bacteria cellulose polyaniline compound. The 114-115 pts. wt. fumaric acid, 70-74 pts. wt. phthalic anhydride, 180-185 pts. wt. N-(6-hydroxyhexyl)isopropanolamine are added into the reactor, stirred for 1 hour, temperature is raised to 150 degrees C, 0.01-0.015 pts. wt. 2.5-di-tert-butylhydroquinone are added, and the temperature is raised to 170-180 degrees C, and 0.05-0.06 pts. wt. antioxidants are added. The 34-37 pts. wt. graphene bacterial cellulose polyaniline compound, 0.5-1 pts. wt. curing agent are added, stirred and mixed, and cooled to 35-50 degrees C to obtain conductive polymer anticorrosive coating of metal grounding grid.
