Advanced Institute of Technology This article will introducePI, PET magnetron sputtering germanium filmThe preparation process and application prospects.

1、 Introduction to PI and PET films

PI (polyimide) film has excellent mechanical properties, high temperature resistance, and chemical stability, and is widely used in fields such as flexible electronics and aerospace; PET (polyethylene terephthalate) film has good transparency, weather resistance, and chemical resistance, making it an ideal substrate material for the preparation of flexible displays, flexible batteries, and other products.

2、 Principle of Magnetron Sputtering Germanium Coating Technology

Magnetron sputtering technology is a coating technique that uses a magnetic field to sputter target materials onto the surface of a substrate material. By controlling the sputtering conditions and the movement of the substrate material, germanium films can be uniformly deposited on the surfaces of PI and PET films, thereby improving the performance and functionality of the films.

3、 Preparation process of PI and PET magnetron sputtering germanium film

1. Preparation: Clean the surfaces of PI and PET films to ensure they are clean and dust-free;

2. Set sputtering parameters: including sputtering power, sputtering time, gas pressure, etc;

3. Start sputtering: Place the germanium target in a vacuum chamber and use measures such as heating and applying high voltage to sputter and deposit germanium atoms on the surface of the film;

4. Control sputtering thickness: By monitoring the thickness of the substrate material surface, control the coating thickness;

5. End sputtering: Stop sputtering after reaching the required coating thickness and allow the film surface to cool.

4、 Application of PI and PET Magnetron Sputtering Germanium Coating

1. Optical devices: PI and PET films coated with germanium film can be used to prepare optical devices such as infrared transmission films and filters;

2. Flexible electronics: The addition of germanium film can improve the conductivity of PI and PET films, making them more widely used in the field of flexible electronics;

3. Membrane material modification: Germanium film can also enhance the wear resistance and chemical resistance of PI and PET films, making them more durable.
