[0020]In parts by weight, successively take 20 parts of graphene oxide, 10 parts of surfactant, and 300 parts of water, pour them into No. 1 beaker, and move No. 1 beaker into an ultrasonic disperser, at a temperature of 65°C, and an ultrasonic frequency of Under the condition of 60kHz, constant temperature and ultrasonic dispersion for 4 hours, the dispersion liquid was obtained, and the dispersion liquid was poured into a ball mill tank, and zirconia ball milling beads were added according to the mass ratio of the ball to material at 20:1, and after ball milling and mixing for 60 minutes, filtered to obtain the filter residue And wash the filter residue 5 times with deionized water, then transfer the washed filter residue to an oven, and dry it to a constant weight at a temperature of 110°C to obtain pretreated graphene oxide; carbon fiber and mass Pour the ethanol solution of silane coupling agent with a fraction of 10% into a three-neck flask with a reflux device, heat and ...
example 2
[0022] Pour the ethanol solution of carbon fiber and 10% silane coupling agent into a three-necked flask with a reflux device at a mass ratio of 1:10, heat and reflux for 5 hours at a temperature of 80°C, and filter to obtain a filter cake , and washed the obtained filter cake with absolute ethanol for 5 times, then transferred the washed filter cake to an oven, and dried it to a constant weight at a temperature of 100°C to obtain a modified carbon fiber; 15 parts of nano-calcium carbonate, 80 parts of linoleic acid, and 30 parts of carbomer were poured into a four-necked flask, and argon gas was passed into the four-necked flask at a rate of 10 mL / min. Under the protection of argon, at temperature Under the conditions of 75°C and a rotating speed of 600r / min, stir and mix at a constant temperature for 60min. During the stirring and mixing process, adjust the pH of the material in the four-necked flask to neutral with a mass fraction of 8% sodium hydroxide solution, and then va...
