[0023]In parts by weight, take 10 parts of aniline, 40 parts of hydrogen peroxide, 300 parts of water, and 0.08 part of biological enzyme, first mix the aniline and water into No. 1 beaker, and move No. 1 beaker into a water bath. Under the conditions of 65°C and a stirring speed of 500r / min, stir and dissolve at a constant temperature for 2 hours, take out the No. Move the beaker to a magnetic stirrer with digital display speed measurement and constant temperature. Under the condition of temperature of 40°C and rotation speed of 500r / min, stir and react at constant temperature for 6 hours, then filter to obtain the filter residue, and wash the filter residue with deionized water for 6 times, and then wash the washed residue The filter residue was transferred to a vacuum drying oven, and was vacuum-dried to constant weight at a temperature of 90°C and a pressure of 120 Pa to obtain low-molecular-weight polyaniline; the graphene oxide and solvent were mixed and poured into a thr...

[0025] According to the mass ratio of 1:20, mix graphene oxide and solvent into a three-necked flask. Under the condition of ultrasonic frequency of 60kHz, after ultrasonic dispersion for 60min, move the three-necked flask to a digital speed measuring constant temperature magnetic stirrer, and the temperature is 85 ℃, the stirring speed is 600r / min, slowly add polyaniline 0.2 times the mass of graphene oxide to the three-necked flask at a rate of 8g / min while stirring at constant temperature, after the polyaniline is added, seal the three-necked flask and continue to keep constant temperature After airtight stirring and reacting for 12 hours, filter to obtain a filter cake, and wash the filter cake 5 times with N-methylpyrrolidone, then transfer the washed filter cake into a vacuum drying oven, at a temperature of 110°C and a pressure of 100Pa, Dry to constant weight to obtain intercalated modified graphene oxide; in parts by weight, take 30 parts of intercalated modified graph...
