The invention discloses a simple and universal method for preparation of a superhydrophobic material. The method includes: firstly placing the matrix of a superhydrophobic material under the action of ozone and ultraviolet lamp irradiation for 0.2-5h, or putting the matrix of the superhydrophobic material in a dopamine aqueous solution to react for 3-24h to hydroxylate the matrix surface; then placing the matrix in an organic solvent solution of chlorosilane with a volume fraction of 0.1%-2% and performing stirring for 0.1-3h; and finally putting the matrix in an oven to perform drying at 20-120DEG C, thus obtaining the superhydrophobic material. According to the invention, the solution stirring method with the characteristics of environmental friendliness, easy large scale production, low cost, wide range of application and simple preparation process is employed to modify the raw material surface and prepare the material with super-hydrophobic performance, and has the advantages of no need for any special and expensive instrument and equipment and accurate test conditions.
