잉크 필름을 준비하는 방법에는 여러 가지가 있습니다., 다음은 일반적인 방법입니다:

스핀 코팅 방식: spin coating method is to pour liquid ink on the rotating substrate, through centrifugal force to make it evenly coated on the surface of the substrate, and then drying at a certain temperature and time, forming ink film. The ink film prepared by spinning coating method is uniform and the thickness is controllable, which is suitable for the preparation of large area film.

Spray method: Spray method is the ink solution through the sprayer evenly sprayed on the surface of the substrate, and then dried at a certain temperature and time. The thickness and shape of the ink film prepared by spray method can be precisely controlled, which is suitable for the preparation of complex shape film.

Flexible printing: Flexible printing is a method of printing ink directly to the substrate surface, and different printing processes can be used, such as letterpress printing, intaglio printing, 스크린 인쇄, 등. The ink film prepared by flexible printing method has the advantages of simple process, low cost and suitable for large area film preparation.

Heat transfer method: Heat transfer method is printing ink on the printing paper, and then transfer the ink to the substrate surface by heat transfer method. The ink film prepared by thermal transfer printing method can achieve very high resolution and pattern complexity, which is suitable for the preparation of high precision film.

Vibration deposition method: vibration deposition method is to soak the substrate in a solution containing ink powder, through high-frequency vibration to make ink powder uniformly deposited on the surface of the substrate, and then drying at a certain temperature and time. The ink film prepared by vibration deposition method is uniform, low cost and suitable for large area film preparation.

Rolling coating method: The use of line coater to prepare the film, the ink is squeezed to the coating substrate, the line coater quickly scraping coating, this method is often used for simple color comparison.

Characteristic distinction
Different preparation methods have different characteristics and advantages and should be selected according to the actual demand and material properties. 예를 들어, the spin coating method is suitable for the preparation of large area uniform film, and the spray method is suitable for the preparation of shape complex

Flexible printing method is suitable for large area and low cost film preparation, thermal transfer method is suitable for high precision and complex pattern film preparation, vibration deposition method is suitable for low cost and large area uniform film preparation, 등.

게다가, different preparation methods still have some limitations and problems that need to be paid attention to. 예를 들어, the thickness of the film prepared by spinning coating is usually thin, and thicker films cannot be prepared. Spray method needs to control the spray pressure and spray head Angle to obtain a uniform film; Flexible printing method needs to choose the appropriate ink and printing materials to avoid the film scratch and fall off problems; The thermal transfer process requires control of the transfer temperature and pressure to obtain a high quality film.

요약하자면, there are a variety of methods to prepare ink film, should be selected according to the actual needs of the appropriate method, and pay attention to reasonable control of preparation parameters, in order to obtain high quality film.
