Device for preparing membrane by liquid level sedimentation method

Abstract

The invention discloses a device for preparing a membrane by the liquid level sedimentation method. The device comprises a container, a heating plate, a liquid storage device and a pipeline, wherein the container adopts a square flat structure and is provided with a liquid inlet; the container is communicated with the liquid storage device through the liquid inlet via the pipeline; and the container is also provided with the heating plate, and the heating plate corresponds to the position of a substrate arranged in the container and used for placing the membrane, and is used for drying and annealing the membrane. The device has simple structure; because the container with the square flat structure is adopted, the liquid consumption is reduced, and the cost of preparing the membrane is effectively lowered; by controlling the sedimentation of the liquid level, the membrane can be conveniently prepared, and the substrate does not need to be moved; and the device can be inclined in any angle, the one-time filming thickness is controllable, and the time for preparing the membrane is shortened.

Description

technical field [0001] The invention relates to a technology for preparing thin films, in particular to a device for preparing thin films by means of a liquid level subsidence method. Background technique [0002] The preparation and research of thin film materials is one of the main subjects of material science research. There are many methods for thin film preparation, such as MOCVD, PECVD, PLD, molecular beam epitaxy, magnetron sputtering, sol-gel method, gel rejection method, Tira method, etc. The thin film preparation method is widely used by thin film researchers due to its simple and cheap equipment. [0003] In the prior art, the pulling method generally adopts such as figure 1 The equipment shown is composed of a barrel-shaped container 2 arranged in a drying box 1, and a motor 3 is arranged on the drying box 1. When preparing a film, the substrate 4 is immersed in the suspension wire 5 driven by the motor 3 into the film. In the drum-shaped container 2 of the fi...
