Abstract

The invention is nickel oxide nano electrochromism film and the manufacturing method, the method uses liquid-gelatum method to produce nickel colloidal sols, them the ITO glass piece is immersed into the liquid, and uses the film device to pull into film, the film can be get through drying, baking, quenching and cooling. The manufacturing method of colloidal sols uses inorganic nickel salt to dissolve in the compound organic solvent which uses waterless alcohol mainly, and they are back flowed every 78-82deg.C, then, adds in water and the organic acid to get the nickel colloidal sols. The invention is simple, the film is even, thick, the even particle radius is between 30-50mm, the light throughput varies in 7.9%-85%. The property of the product is stable.

Description

1. Technical field [0001] The invention relates to a color-changing thin film attached to a device and a preparation method thereof, in particular to a nickel oxide electrochromic thin film and a preparation method thereof. 2. Background technology [0002] There are many ways to prepare electrochromic thin films of nickel, including anodic oxidation, electrochemical deposition, electron beam evaporation, sputtering, high temperature direct oxidation and so on. However, these methods require large-scale equipment, the preparation process is complicated, and the film-forming area is limited by the equipment, so they are not suitable for large-scale preparation. [0003] At present, most of nickel oxide nano-electrochromic thin films are prepared by sol-gel method by hydrolysis of nickel alkoxide. However, the traditional formulations for preparing nickel oxide sol are relatively complicated, which makes the preparation process of nickel oxide electrochromic thin film also ve...
