Background
In recent years, nano materials such as metal organic frameworks, carbon nanotubes, graphene, silicon dioxide, titanium dioxide and the like are widely applied to the fields of nano electronic devices, medical health, aerospace, biotechnology and the like. In order to improve the chemical reactivity, dispersibility and other properties of the nanomaterial, chemical modification is required. For example, the specific surface area and the surface energy of the carbon nanotubes are large, the carbon nanotubes are agglomerated and bent and entangled together by stronger van der Waals force, the reinforcing effect of the carbon nanotubes on the composite material is reduced, and the carbon nanotubes can be subjected to amination chemical modification in order to uniformly disperse the carbon nanotubes in a polymer matrix and form stronger interface bonding strength with the polymer; for another example, in order to ensure the interface combination of graphene and a matrix material, or to utilize the functional groups on the surface of graphene to perform a composite reaction with other materials, amino groups, carboxyl groups and other groups can be introduced on the surface of graphene through chemical modification. In general, modification of the nanomaterial may better perform the nanomaterial itself.
However, these chemically modified nanomaterials have poor stability in harsh environments such as strong acids, strong bases or high salts, and are greatly limited in application in some special fields, because the hydrophobic properties of the materials are poor (the contact angle is generally lower than 90 °), so that the pore channels are in contact with water in a large amount, and the surfaces of the materials are soaked by the water to reduce the properties.
Therefore, improvements are needed.

As can be seen from FIGS. 4 to 10, the super-hydrophobic modified nanomaterial of the present invention has a contact angle of 160 ° or more, and exhibits good super-hydrophobic properties.
The super-hydrophobic modified nanomaterial obtained in examples 1-7 is subjected to oil-water separation test, and the test method comprises the following steps: filling the super-hydrophobic modified nano material on a narrow head of an injector by taking a cotton layer as a support as a separation device, injecting a dichloromethane/water mixture into the injector, and rapidly separating the layered dichloromethane/water mixture under the gravity. The oil-water separation efficiency was the ratio of the weight of collected methylene chloride to the weight of methylene chloride before separation, and the results are shown in FIG. 11.
As can be seen from fig. 11, the superhydrophobic modified nanomaterial shows a good dichloromethane/water separation capability, and the separation efficiency is about 99%.
