[0021]Mix bentonite and water at a mass ratio of 1:10, and stir and mix for 50 minutes at a temperature of 55°C and a rotational speed of 400r / min to obtain a bentonite dispersion. : 1 mixed in a beaker, and in the beaker, add a silane coupling agent of 0.12 times the quality of the bentonite dispersion liquid, under the condition of 55kHz frequency, after ultrasonic dispersion for 2h, filter to obtain a filter cake, grind the filter cake to obtain a pre- To treat the modified bentonite, mix the pretreated modified bentonite with cetyltrimethylammonium bromide in a mass ratio of 5:1, and add the mixture of pretreated modified bentonite and cetyltrimethylammonium Add water 15 times the mass of the pretreated modified bentonite, stir and mix for 5 hours at a temperature of 80°C and a speed of 280r / min, and then filter to obtain a modified bentonite blank. The modified bentonite blank is heated at a temperature of 70°C After drying for 3 hours under certain conditions, the modifi...

[0023] Mix graphene oxide and absolute ethanol in a flask at a mass ratio of 1:110, and ultrasonically disperse for 2 hours at a frequency of 55 kHz, then add ferric chloride and graphite oxide that are three times the mass of graphene oxide into the flask Sodium acetate whose mass is 6 times that of ethylene is stirred and mixed for 2 hours at a temperature of 60°C and a rotating speed of 400r / min, and the material in the flask is kept for 6 hours at a temperature of 200°C, and the material is cooled and discharged to obtain Graphene oxide mixture, the graphene oxide mixture is washed with deionized water until there is no chloride ion in the washing liquid, and then dried at a temperature of 100°C for 60 minutes to obtain a precursor; aniline and 10% hydrochloric acid are Mix in a three-necked flask with a mass ratio of 1:60, and add a precursor of 0.05 times the mass of aniline to the three-necked flask. Stir and mix for 50 minutes at a temperature of 5°C and a rotational sp...
