NOVELTY - Preparing modified graphene oxide involves taking proper amount of modified graphene oxide, preparing dispersion of 2 g/l graphene oxide, dispersing for 2 hours under the ultrasonic condition, weighing 1000 g of graphene oxide dispersion liquid, putting in the reaction kettle, stirring, heating in water bath at 70 degrees C, weighing the 4 g vinyl triethoxy silane, adding into the reaction kettle by dropping for 0.5 hours, continuously reacting for 1 hours after dropping, allowing to stand and cooling, ending the test. USE - Method for preparing modified graphene oxide. ADVANTAGE - The method effectively weakens the graphene oxide to the tackifying effect of the concrete, and improves the utilization rate of the graphene oxide.
