Method for preparing patterned functional film based on template deposition

Abstract

The invention relates to a method for preparing a patterned functional film based on a template deposition, and aims to solve the technical problem that degradation efficiency and light absorbance utilization efficiency are relatively poor as a film prepared by existing similar methods is relatively difficult to realize stored oil lubrication in surface pits, is relatively poor in wear resistanceand anti-friction quality, is relatively small in specific surface area and is relatively difficult to realize selective absorption and reflection of visible light. The key point is that the method comprises the following steps of: preparing a surface nano structure with a nano tube array structure on metal surfaces such as a titanium surface and an aluminum surface through an anode oxidization technology; removing the surface nano tube structure through a chemical or mechanical method, and leaving a patterned template structure on a metal matrix surface; and conducting depositing on a metal patterned surface through a physical gas-phase deposition technology to prepare a functional film. The functional film deposited by the method has a patterned morphology, can improve binding force between the film and matrix, can increase a specific surface area of the film, and is beneficial for bringing functional effects such as photocatalysis of the film into play.

Description

Technical field [0001] The invention relates to a functional film, in particular to a method for preparing a patterned functional film based on template deposition. Background technique [0002] A film is a thin and soft transparent sheet made of plastic, adhesive, rubber or other materials. The scientific explanation is: a two-dimensional material formed by atoms, molecules or ions deposited on the surface of the substrate. Functional film is a kind of film that is widely used in friction and wear, photocatalysis, photovoltaic and other fields. Some of the functional films are titanium dioxide films. Titanium dioxide due to its high refractive index and relative robustness, this high refractive index material is used in the visible and near infrared regions, almost every TiO 2 The vaporization follows a principle: to obtain negligible absorption in the usable spectral region, which can reduce the limitation of oxygen pressure and the limitation of temperature and vaporization sp...

Problems solved by technology

[0003] In order to overcome the above-mentioned deficiencies, the purpose of the present invention is to provide a method for preparing patterned functional thin films based on template deposition in the field, so that it can solve the problem that it is difficult for the thin films prepared by the existing similar methods to achieve oil storage lubrication and wear resistance in the surface pits. Poor friction reduction and small specific surface area make it difficult to achieve selective absorption and reflection of visible light, resulting in poor degradation efficiency and light absorption and utilization efficiency.
