Device for preparing nanometer functional films on substrate surfaces by use of sol-gel method

Abstract

The invention provides a device for preparing nanometer functional films on substrate surfaces by use of a sol-gel method, which relates to a device for preparing films. The device comprises a precursor liquid container 8, a big container 6, a liquid conduit 14, a high-position precursor liquid bottle 15, a shock absorption base 2 and a bracket 19, wherein a porous cylinder 4 is placed on the bottom of a container and is coaxial with the big container 6; a gap between the big container 6 and the porous cylinder 4 is filled with silica gel to the height of the cylinder; the precursor liquid container 8 is arranged in the cylinder 4 and is coaxial with the big container 6 and the porous cylinder 4; a movable beam is arranged above the bracket; a caliper is arranged on the right side of the beam; and the caliper sticks the high-position precursor liquid bottle 15. The device can be used to prepare uniform transparent nanometer functional films which are firmly combined with surfaces on the cleaned surfaces of the substrate by taking colloidal solution of each component as precursor solution, and is widely used in laboratories for preparing various functional films, such as electrochromic films, transparent conductive films, photocatalytic films, self-cleaning films, photoelectric or electro-optic films and the like.

Description

technical field [0001] The invention relates to a device for preparing a film, in particular to a device for preparing a uniform and transparent nanometer functional film on the surface of a substrate by using a sol-gel method. Background technique [0002] Thin film material is a kind of advanced material with special structure and performance and extremely wide application fields widely studied in modern scientific research and high-tech fields. Due to the different fields of researchers, the types of thin films studied are also different, and their application fields are also different, but their common problem is: to prepare uniform and transparent nano-functional films that are firmly combined with the substrate on the surface of the required substrate. Films are very difficult. Due to the low preparation efficiency of the thin film, it seriously hinders the research progress of the subject. The main reasons are as follows: 1. The colloidal solution as a film-forming ...

AI Technical Summary

Problems solved by technology

Due to the different fields of researchers, the types of thin films studied are also different, and their application fields are also different, but their common problem is: to prepare uniform and transparent nano-functional films that are firmly combined with the substrate on the surface of the required substrate. film is very difficult

Controlling these factors is difficult without proprietary devices and techniques

③Because there is no proprietary device and technology, there is no suitable constant relative motion speed between the colloid solution and the substrate during the film formation period, so there is no basis for forming a uniform film; ④In the past, instruments, equipment or The motor and other electric components are used in the device, and the vibration of its operation seriously affects the uniformity of film formation

There are currently no disclosed specifically suitable instruments, equipment and devices
