Method for preparing a composite material having a high adhesion superhydrophobic film

The present invention discloses a method for preparing a composite material having a high adhesion superhydrophobic film, first, the TEOS was added to a mixture of catalyst and an alcoholic solvent, the reaction of nano-silica. Then, the benzene solvent is added in the nano silica, a silane coupling agent added to the amino group, to obtain amino-modified nanosilica. The carbon nanotubes, thionyl chloride, N, N- dimethylformamide was placed in a single neck flask, reflux reaction of the acid chloride of the multi-walled carbon nanotubes. Finally, the amino-modified nanosilica, acylation MWCNTs, stearate was added to the benzene solvent, prepared by reacting stearic acid reflux grafted MWCNTs / nano- silicon oxide composite material, said composite material after ultrasonic dispersing material is an inorganic or organic base, to obtain the composite material having a high adhesion superhydrophobic film by a coating method; simple preparation process, good repeatability, low cost, easy to promote the use of.
