Problems solved by technology

As a result, the DC reaction magnetron cathode cannot start the arc, cannot maintain the normal glow discharge, and the magnetron sputtering will not be able to proceed.
In order to continue to deposit the NiO anode electrochromic film, only the oxides on the target surface of the sputtering cathode and various baffles in the vacuum box must be cleaned frequently, which will inevitably lead to low production efficiency and high cost, which is not conducive to large-scale continuous Production

Abstract

The invention discloses a magnetron sputtering based production technology of a NiO electrochromic film. The technology is performed based on a vertical continuous vacuum magnetron sputtering device. The technology comprises the following steps: depositing an ITO nano film layer on a glass substrate by a DC magnetron sputtering method; and then depositing a NiO anodic electrochromic film on the ITO nano film layer through the DC magnetron sputtering method. The technology has the beneficial effects that the adhesive force of the film to a substrate is high; the film obtained by sputtering is high in purity; the density and filming uniformity are high; and the sputtering technology is high in repeatability.

Description

technical field [0001] The invention relates to a magnetron sputtering process, in particular to a magnetron sputtering-based NiO electrochromic film production process and glass prepared by the process. Background technique [0002] Electrochromism refers to the reversible color change under the action of external electric field and current. Electrochromic thin films are very attractive in the fields of electrochromic storage devices, buildings, vehicles, ships and airplanes, non-glare mirrors, smart windows, and electrochromic displays in the fields of building energy saving, military anti-counterfeiting and information display. For example, smart windows can selectively absorb or reflect external heat radiation and prevent internal heat diffusion, so that buildings can obtain the best lighting while minimizing energy consumption. The characteristics of pollution and intelligence. In recent years, with the enhancement of people's awareness of energy saving and environmen...
