The invention discloses an organic polysilazane/inorganic nano material super-hydrophobic coating and a preparation method thereof. The preparation method is as follows: firstly prepare an organopolysilazane solution, and use a silane coupling agent containing a hydrophobic unit to carry out hydrophobic treatment on the inorganic nanomaterial to prepare a dispersion liquid of the hydrophobic inorganic nanomaterial; then use an organic, inorganic or metal material As the base material, organopolysilazane and hydrophobic inorganic nanomaterials are alternately deposited on the surface of the base material by a deposition method; finally, appropriate heat treatment can be performed on the surface after multiple alternate depositions. The coating obtained by the present invention shows good superhydrophobic properties, the water drop contact angle on its surface is greater than 150°, the rolling angle is less than 10°, has good mechanical and chemical stability, and can be used in waterproof clothing, exterior wall coatings, oil-water separation, Biomedical and other fields have broad application prospects. The method not only has a simple preparation process, but also can construct a large-area super-hydrophobic coating on the surface of various substrates. |
