Problems solved by technology

Because this method affects the line of sight, it is mainly used on the rear windshield of the car and cannot be used on the front windshield
The defogging of the front windshield mainly depends on blowing, which is less effective and efficient

Abstract

The present invention relates to a method for preparing nano multilayer film on glass surface. Said invention utilizes the combination of sol-gel method and spray pyrolysis method to prepare first layer silicon dioxide film, second layer antimony-fluorine combination doped tin dioxide film and third layer composite film using silicon dioxide and titanium dioxide as main component. Said invention also provides the concrete function of the above-mentioned energy layer film, and said glass has the hydrophobic and bacteriostatic characteristics.

Description

technical field [0001] The invention relates to a preparation method of a glass surface film, in particular to a preparation method of a glass surface nanometer multilayer film. Background of the invention [0002] The transparent conductive substrate used in liquid crystal, plasma and other flat panel display devices in the optoelectronics industry is to prepare a layer of oxide transparent conductive film on the glass surface. There are many types of oxide transparent conductive films, such as: doped tin oxide, Doped zinc oxide and tin-doped indium oxide (ITO), etc. In industrial applications, taking into account both electrical conductivity and light transmission, this type of thin film is currently mainly made of tin-doped indium oxide (ITO). Due to the rare element indium, the cost is relatively high. Its preparation methods mainly adopt magnetron sputtering, chemical vapor deposition, sol-gel method, spray pyrolysis method, etc., among which: magnetron sputtering and ...
