A brush printing film-making device and a nano-film printing method based on the device

Abstract

A writing brush printing filming device and a nano film printing method based on the device. The writing brush printing filming device comprises a writing brush device. The writing brush device comprises an outer liquid supply tube (1), a tightening tube (2), and an inner liquid supply tube (3). A plurality of protruding brush hair (5) is fixedly disposed on the inner wall of the inner liquid supply tube (3). The plurality of protruding brush hair (5) is divided into two parts. The two parts are correspondingly disposed on relative inner walls of the inner liquid supply tube (3), and tips of the two parts of the protruding brush hair (5) are intersected and put together. A circle of liquid storage hair (4) is fixedly disposed on the outer wall of the inner liquid supply tube (3) surrounding the inner liquid supply tube (3), the outer liquid supply tube (1) is sleeved on the liquid storage hair (4), the tightening tube (2) is sleeved on the outer liquid supply tube (1), and the outer liquid supply tube (1) and the inner liquid supply tube (3) in which the liquid storage hair (4) and the protruding brush hair (5) are fixed are fixed by means of the tightening tube (2), so that the protruding brush hair (5) and the liquid storage hair (4) are combined into a conical fiber writing brush point. The ultra-long functional nano film prepared by using the writing brush printing filming device has good repeatability.

Description

technical field

[0001] The invention belongs to the technical field of functional materials. Specifically, the invention relates to a brush printing film forming device and a nanometer film printing method based on the device. Background technique

[0002] Thin film materials are two-dimensional materials formed by depositing atoms, molecules or ions on the surface of a substrate. Membrane materials (or thin films) involve a wide range of manufacturing and application fields, including building materials, energy conservation and environmental protection, medicine, electronics, food, transportation, energy, chemicals and other industries. For example: protective barrier film, including card protection film, solar cell film, etc.; optical film, including liquid crystal display film, photosensitive film, etc.; electronic and electrical film, such as capacitor film, antistatic film, insulating film, etc. Inspired by the transfer control of brush ink in traditional Chinese paint...
