Embodiment Construction

[0044] Such as Figure 3 to Figure 5 As shown, the film spraying machine involved in the present invention is mainly composed of a three-dimensional electric adjustment frame, a post-processing tank 22, a cover plate 26, and a controller 36. The first motor 1, the second motor 2 and the third motor 3 are controlled by the controller 36, so as to realize the movement of the nozzle 21 in three-dimensional space; the opening of the ultrasonic generator 23 and / or the electric heating jacket 39 is controlled by the controller 36; The opening and closing of the nozzle is controlled by the air solenoid valve 32 ; the temperature of the film-forming substrate 34 is controlled by the temperature sensor (not shown in the figure) and the electric heating plate 9 .

[0045] Such as Figure 5 As shown, the solution pipe interface 19 is connected to the solution bottle 31, one end of the air solenoid valve 32 is connected to the compressed air pipe interface 20, and the other end is connec...

Abstract

The invention discloses a thin film spray coating machine, which comprises a spray head, and is characterized in that: the spray head is fixed on a three-dimensional adjusting frame and can move in a three-dimensional way; a post-treatment tank is arranged below the spray head; the bottom of the post-treatment tank is provided with a heat conducting plate; an electric heating plate is arranged below the heat conducting plate; and the post-treatment tank and a cover plate form a closed space. The invention also discloses a thin film preparation method, which comprises the following steps of: spray coating in the post-treatment tank to form a thin film; and then directly performing solvent vapor infiltration post-treatment on the thin film in the post-treatment tank. The thin film spray coating machine provided by the invention can be used for preparing a large-area thin film with uniform thickness, small error, high accuracy and adjustable shape and has high filming repeatability. Heating and solvent infiltration treatment functions are integrated; and laboratory film preparation and small-scale industrial film preparation are facilitated.

Description

technical field [0001] The invention relates to the field of film preparation and post-treatment, in particular to a film spraying machine and a film preparation method. Background technique [0002] Spraying technology is a coating method in which the paint is atomized by means of a spray gun and other spraying tools, and then sprayed onto the workpiece to be coated. Generally used in hardware, plastics, furniture, military industry, ships and other fields. In recent years, it has also been widely used in the field of large-area organic photovoltaic thin film preparation. However, the existing spraying devices have their specific application objects, have limitations in the field of changing the morphology of thin films, and are not suitable for preparing organic photovoltaic thin films. As shown in the literature of Advanced Functional Materials (Adv. Funct. Mater, 2010, 20, 3538), the films prepared by electrostatic spraying method generally have large particle island-l...
