I. Introduction

With the continuous development and popularization of display technology, liquid crystal dimming film, as a new type of optoelectronic material, is increasingly used in display devices, optical devices and other fields. As the key preparation equipment of liquid crystal dimming film, the selection of laboratory coating machine directly affects the performance and quality of liquid crystal dimming film. Therefore, the correct selection of a suitable laboratory coating machine is of great significance for the research and production of liquid crystal dimming films.

2. Selection principles of laboratory coating machines in the application of liquid crystal dimming films

1. Coating method: Select the appropriate coating method according to the characteristics and application requirements of the liquid crystal dimming film. Common coating methods include spin coating, spray coating, scraping coating, etc.

2. Coating thickness control: The performance of the liquid crystal dimming film is closely related to the thickness of the coating, so it is necessary to choose a coating machine with precise coating thickness control function.

3. Coating speed: Considering production efficiency and coating quality, choose a coating machine with adjustable coating speed to meet different process requirements.

4. Temperature control: During the preparation process of liquid crystal dimming film, temperature has a great influence on the quality and performance of the coating film, so it is necessary to choose a film coating machine with precise temperature control function.

5. Material compatibility: Considering the material characteristics of the liquid crystal dimming film, choose a coating machine that is compatible with the liquid crystal dimming film material to ensure the quality and stability of the coating film.

6. Operation convenience: Choose a film coating machine that is simple to operate and easy to control to improve work efficiency and production quality.

3. Technical analysis of laboratory coating machines in the application of liquid crystal dimming films

Spin coating machine: The spin coating machine is suitable for the preparation of liquid crystal dimming films. The coating process is realized by rotating the base material and the coating material relative to each other. Its advantage is that the coating has high uniformity and is suitable for preparing large-area liquid crystal dimming films, but the coating speed is relatively slow.

Spray coating machine: The spray coating machine uses spray technology for coating, and is suitable for the preparation of liquid crystal dimming films. The advantage is that the coating thickness is adjustable and is suitable for the preparation of liquid crystal dimming films of different thicknesses, but the uniformity of the coating film is relatively poor.

Blade coating machine: The blade coating machine applies the coating material evenly on the surface of the base material through a scraper, and is suitable for the preparation of liquid crystal dimming films. Its advantage is that the coating thickness can be precisely controlled and is suitable for preparing thinner liquid crystal dimming films, but the coating speed is relatively slow.

Vacuum deposition coating machine: The vacuum deposition coating machine uses vacuum evaporation or sputtering technology for coating, and is suitable for the preparation of high-precision and high-performance liquid crystal dimming films. The advantage is that the coating quality is high and it is suitable for preparing high-demand liquid crystal dimming films, but the equipment cost is high.

4. Conclusion

The correct selection of a suitable laboratory coating machine is of great significance to the research and production of liquid crystal dimming films. During the selection process, factors such as coating methods, coating thickness control, coating speed, temperature control, material compatibility, and ease of operation need to be considered to meet the preparation requirements for liquid crystal dimming films. At the same time, according to the performance and application requirements of the liquid crystal dimming film, select the appropriate type of coating machine to improve the quality and stability of the liquid crystal dimming film.
