preparation example Construction

[0018] Aiming at the problems in the preparation of graphene composite materials in the prior art, the present application provides a preparation method of graphene oxide-brillonite composites, which has the advantages of safe preparation process, high single output and short preparation time . Specifically, the embodiment of the present invention discloses a preparation method of a graphene oxide-brillonite composite, comprising the following steps:

[0019] The zinc sulfate heptahydrate and the urea are reacted in water for the first time, and then the graphene oxide dispersion liquid is added, and the reaction is performed again to obtain the graphene oxide-brillonite composite.

[0020] In the above-mentioned preparation process, the present application firstly prepared bryantite, but bryantite was not directly prepared in one step, specifically, the primary reaction of zinc sulfate heptahydrate and urea in water, more specifically, the primary reaction It can be carried ...

Embodiment

[0026] Dissolve 1g of heptashui, zinc sulfate and 3g of urea in 100g of water. After the solution is completely dissolved, pour the solution into a three-necked flask, raise the temperature of the oil bath to 95 °C, and put the three-necked flask into the oil bath. Start the reaction, the three-necked flask needs to be connected to a serpentine condenser during the reaction, so that the water content in the solution remains unchanged as much as possible, which is beneficial to the stability of the product;

[0027] Prepare graphene oxide dispersion liquid while the above reaction is carried out, dissolve 0.01g~0.08g of graphene oxide in 20g of water, and ultrasonicate for more than 1 hour; after 5 hours of oil bath reaction, add graphene oxide to the three-necked flask The dispersion liquid was kept at 95°C and reacted for another 1 h, then the three-necked flask was taken out from the oil bath, cooled naturally, the precipitate was taken out, and the final product was obtained...
