Construction method of titanium surface micrometre-grade pattern based on ultra-hydrophilic/ultra-hydrophobic characteristic

Abstract

The invention discloses a construction method of titanium surface micron-size picture based on super hydrophilic / super hydrophobic peculiarity, which comprises the following steps: pre-processing the surface of base material; allocating electrolytic solution; controlling voltage and temperature; proceeding electro chemical anodic oxidation; getting titanium oxide nanometer structure array film layer; proceeding heat treatment; getting example; soaking in fluorine silicane methanol solution at 10-240 min; getting out; drying at 120-160 deg.c; getting super hydrophobic TiO2 nanometer structure array film layer; covering photomask; irradiating with ultraviolet light; getting the final picture.

Description

technical field

[0001] The invention relates to a titanium surface, in particular to a new method for preparing micron-scale super-hydrophobic-super-hydrophilic patterns based on the construction and modification of titanium dioxide nanostructure film layers on the surface of titanium or titanium alloys. Background technique

[0002] Titanium dioxide is a semiconductor material with broad application prospects. Its excellent physical and chemical properties make it have attractive application prospects in solar cells, photocatalytic degradation of pollutants, sensors, and glass anti-fog. It has become a research topic at home and abroad. a hot spot. The current preparation methods of titanium dioxide film layer include hydrothermal method, plasma spraying, electrodeposition, electrochemical anodic oxidation method, sol-gel method and so on. Among them, electrochemical anodic oxidation (anodic oxidation) is a surface treatment method with low cost, simple operation and stron...
