The white semitransparent TPE-SiO2 composite film is prepared by doping finished nanometer SiO2 particles into TPE, the properties of the composite film are changed by adding SiO2, and the film forming stability and the surface hydrophobicity are improved. When the mass ratio of SiO2 to TPE is 17.5%, the composite film has the best comprehensive performance, the surface water contact angle reaches 145 degrees, and the tensile strain reaches about 750 percent. And the composite film not only has good hydrophobicity in a normal state, but also has good hydrophobicity in stretching extension and cyclic stretching. The composite film also has good effects in low adhesion and acid resistance. Subsequently, the dahlia-shaped Co3O4 particles are prepared by a hydrothermal synthesis method, and the provided rough structure not only has changed surface wettability, but also has good effects on low adhesion, underwater oil absorption and various oil-water separation. The black TPE-Co3O4 composite film prepared by independently doping the prepared Co3O4 particles into TPE can realize super-viscous super-hydrophobic performance in ultraviolet laser etching, and the surface water contact angle can reach about 150 degrees.
