NOVELTY - Peparing a conductive film involves taking 3-5g single-walled carbon nanotube, 1-3g graphene, 1-2g nickel-chromium alloy powder, 30-40ml concentrated sulfuric acid and 10-15ml concentrated hydrochloric acid, placing in ultrasonic cleaner at 100-120W at room temperature for 20-30 minutes, and placing it in oil bath condenser under reflux condition at 80-90 degrees C for 4-5 hours to obtain condensed material. The obtained condensed material is cooled to room temperature, washed with deionized water, and then freeze-dried to obtain freeze-dried material. USE - Method for peparing a conductive film. ADVANTAGE - The method enables to prepare a conductive film, which has good mechanical property, good barrier properties, and high conductivity. DETAILED DESCRIPTION - Peparing a conductive film involves taking 3-5g single-walled carbon nanotube, 1-3g graphene, 1-2g nickel-chromium alloy powder, 30-40ml concentrated sulfuric acid and 10-15ml concentrated hydrochloric acid, placing in ultrasonic cleaner at 100-120W at room temperature for 20-30 minutes, and placing it in oil bath condenser under reflux condition at 80-90 degrees C for 4-5 hours to obtain condensed material. The obtained condensed material is cooled to room temperature, washed with deionized water, and then freeze-dried to obtain freeze-dried material. The obtained is added with 30-40g chlorinated polypropylene, 10-20g low density polyethylene, 10-30g polyhydroxyalkanoate, 5-10g polyanionic cellulose, 2-3g zinc oxide powder, 0.5-1g gallium oxide powder, 1-2g phenolic hydrolyzed lignin, 2-5g polyurea, 4-6g phosphate, 1-2g dibutylhydroxytoluene, 3-6ml epoxidized soybean oil and 2-4g bentonite which is added in high-speed mixer at a speed of 400-600 revolutions per minute for 30-40 minutes to obtain stirred material. The obtained stirred material is subjected to extrusion granulation in a twin-screw extruder at a temperature of 155-160 degrees C, 160-165 degrees C, 160-165 degrees C, 160-165 degrees C, and 160-165 degrees C, and speed of 60-70 revolutions per minute to obtain extruded material. The obtained extruded material is injected in injection molding machine for injection molding at a temperature of 155-165 degrees C and pressure of 20-30MPa for 5-10 seconds to obtain final film.
