Problems solved by technology

These two methods have many disadvantages, such as the spin coating method cannot control the film thickness well, the manual soaking method cannot obtain a good shape due to the influence of the edge tension of the substrate, and these two methods are time-consuming and labor-intensive, and it is difficult to accurately control the preparation time , the prepared film has poor reproducibility and cannot be prepared in large quantities

Embodiment 1

[0071] The invention provides a device for fully automatic spraying film preparation, which includes a gas supply system, a gas regulating system, a pressure vessel, a numerical control system, an atomizing nozzle, a base support frame and an external box. The schematic diagram of the device is as figure 1 As shown, the working principle diagram is attached Figure 8 shown. The atomizing nozzle and the base support frame are located inside the box and directly participate in the spraying and film formation; the rest should avoid direct contact with the spray and can be arranged outside and above the box.

[0072] In order to facilitate the operation of the internal device, one side of the external box is made of metal, and the other side is made of transparent PMMA plastic. There is also a push-pull door to facilitate the adjustment of parameters such as the placement of the base and the angle of the bracket at any time.

Embodiment 2

[0079] The metal-organic framework (taking the classic HKUST-1 as an example) thin film is prepared by using the device described in Example 1 above, and the device is selected according to the laboratory with a smaller size such as 50*50*50cm (length / width / height) , while the gas supply system uses a standard pure nitrogen cylinder, which specifically includes the following steps:

[0080] Prepare raw material solutions: weigh copper acetate and trimesic acid, dissolve them in pure ethanol solutions, and prepare 500 mL of ethanol solutions with concentrations of 1 mmol / L and 0.4 mmol / L respectively.

[0081] Preparation stage: Pour the prepared copper acetate ethanol solution and trimesic acid ethanol solution into container 1 and container 2 in sequence, container 4 contains 500mL of alcohol (for rinsing the substrate), container 3 is empty, container 1- 4 are made of stainless steel. Set the program through the console of the numerical control system: copper acetate ethano...

Abstract

The invention provides a full-automatic spray type device for preparing a film. The device prepares a film on the surface of a substrate by using a full-automatic alternate spray liquid phase epitaxymethod. The device comprises a gas supply system, a gas regulation system, a pressure container, a numerical control system, an atomizing spray head, a substrate support frame and an external box body. According to the device, corresponding parameters can be set for the control system according to requirements, different raw materials can be accurately and uniformly sprayed to cover the substrate,and the contact reaction time of each raw material and the substrate can be regulated and controlled, so that the film with excellent appearance and consistent orientation, particularly the layer-by-layer self-assembly film material is effectively prepared. The device has the advantages of being fully automatic, high in precision, labor-saving and the like, and is particularly suitable for preparation of large-area, multi-layer repeated and complex-component metal-organic frame (MOFs) films.

Description

technical field [0001] The invention belongs to the technical field of full-automatic film production, and in particular relates to a fully automatic spray-type film preparation device. Background technique [0002] Thin film materials are widely used in the fields of sensors and devices due to their good performance and applicability. In particular, thin film materials assembled by layers have good surface morphology and controllable film thickness, so they have good application prospects in the fields of electronics, optics, catalysis and protection. However, how to efficiently prepare high-quality layer-by-layer assembled films is still a great challenge. At present, there are two main methods used to prepare thin films: spin coating method and manual immersion method. These two methods have many disadvantages. For example, the spin coating method cannot control the film thickness well, and the manual soaking method cannot obtain a good shape due to the influence of the...
