Abstract

The invention relates to a preparation method for preparing super-amphiphobic composite materials and particularly relates to a preparation method for preparing a sugarcoated haw-shaped super-amphiphobic composite material. The method comprises the steps of 1) adding 0.05-0.3 part of a tellurium nanowire into 10-25 parts of anhydrous ethanol in weight part, and magnetically stirring an obtained solution for 10-80 minutes; 2) adding 0.1-1 part of ammonia water and 0.05-2 parts of deionized water into the solution obtained in the step 1) in weight part, and continuously stirring the obtained solution for 1-25 minutes; 3) sequentially adding 12-30 parts of TEOS / anhydrous ethanol mixed solution and 1-20 parts of perfluorooctyl triethoxysilane in the above solution obtained in the step 2) in weight part, continuously stirring the obtained solution for 1-3 hours after the adding process, washing the obtained solution with water and anhydrous ethanol after the reaction respectively, and drying at the temperature of 60 DEG C, wherein the volume ratio of TEOS to anhydrous ethanol in the TEOS / anhydrous ethanol mixed solution is 1:10. In this way, the sugarcoated haw-shaped super-amphiphobic composite material is obtained. The obtained sugarcoated haw-shaped super-amphiphobic composite material is good in mechanical properties, stability and fastness, and free of the separation from a functional surface. Meanwhile, the material is simple in preparation process, easy in condition control and convenient for mass production.

Description

technical field [0001] The invention relates to a preparation method of a super-amphiphobic composite material, in particular to a preparation method of a candied haws-shaped super-amphiphobic composite material. Background technique [0002] The super-amphiphobic surface refers to the surface whose contact angle with water and oil is greater than 150°C. It has great application prospects in industrial production and even in people's life. For example, super-amphiphobic materials can be applied to glass instruments to achieve self-cleaning effects. If applied to oil pipeline transportation, it can greatly reduce the adhesion of oil to pipelines, reduce energy consumption and pipeline blockage during transportation. Superamphiphobic materials can also be applied to the hull of ships and the surfaces of various storage tanks to achieve anti-corrosion and anti-pollution effects. At present, people have prepared super-amphiphobic materials through various methods and means. For...
