Problems solved by technology

[0005] However, the aforementioned methods require a considerable amount of time in the process of anodizing and duplicating the polymer substance, and realize an extremely hydrophobic surface only with the polymer substance, so that the surface strength is weak compared with a metal surface
Moreover, it is necessary to attach replicated polymer substances on the surface of the article to achieve an extremely hydrophobic surface, so it is difficult to apply to the surface of a complex and three-dimensional article

Abstract

The invention provides a method for processing a super-hydrophobic surface having superior surface strength, and an evaporator having the super-hydrophobic surface processed by same. The method for processing a super-hydrophobic surface according to the invention includes: a step of preparing a metallic base material; a step of anodizing the metallic base material to form a ceramic layer having a complex structure of a micro structure and a nano fiber structure on a surface of the metallic material; and a step of applying a hydrophobic polymer material on the complex structure to form a polymer layer having the same surface shape as that of the complex structure.

Description

technical field [0001] The present invention relates to a method of processing an extremely hydrophobic surface, and in more detail relates to a method of processing an extremely hydrophobic surface excellent in surface strength and an evaporator having a hydrophobic surface processed by the method. Background technique [0002] The surface of the lotus leaf is a structure in which nano-protrusions with a size of hundreds of nanometers are arranged on the surface of micro-protrusions with a size of ~10 μm, which has extremely hydrophobic and self-cleaning functions. There are known methods for replicating micro-nano composite protrusion structures from substances with low surface energy and processing extremely hydrophobic surfaces by various methods. Extremely hydrophobic surfaces have the advantage of small contact angle hysteresis (difference between advancing and receding angles), and thus can be applied in various industrial fields. [0003] Among the known methods for...
