Title:
SUPER-HYDROPHOBIC MATERIAL, PREPARATION METHOD THEREFOR AND APPLICATION THEREOF
Document Type and Number:
WIPO Patent Application WO/2021/087982
Kind Code:
A1
Abstract:
A super-hydrophobic material, a preparation method therefor and an application thereof. A hydrophobic surface of the super-hydrophobic material is composed of a positive surface energy material, a negative surface energy material and micro-nano voids. The super-hydrophobic material has a super-hydrophobic performance by means of introducing the negative surface energy material and a micro-nano void design on the hydrophobic surface without using low-surface-energy organic substances. Moreover, since no organic substances are used, the super-hydrophobic material has good temperature and weather resistance, and excellent wear and corrosion resistance.
