Abstract

The invention provides a film preparation device and preparation method based on ink-jet printing. A top plate and a bottom plate which are correspondingly arranged are adopted, nozzle arrays which face the bottom plate and are controlled by a control device are installed on the lower end face of the top plate and jet reagents to a substrate arranged on the upper end face of the bottom plate, and then film is prepared. The film preparation device is simple in structure, the film preparation method is simple in technological process and convenient to operate, and then the film preparation efficiency and quality can be effectively improved.

Description

technical field [0001] The invention relates to the technical field of thin film preparation, and more specifically, to a thin film preparation device and method based on inkjet printing technology. Background technique [0002] Graphene is a new type of two-dimensional inorganic nanomaterial developed in recent years. Due to its extremely high mechanical strength, excellent electrical and thermal conductivity, and rich sources, it is widely used in various fields such as chemistry, physics, materials, and electronics. with broadly application foreground. However, there are many problems in the industrial application of graphene, among which the large-scale preparation of graphene is one of the main challenges. [0003] Graphene oxide is the oxide of graphene. Because it is very similar to graphene in structure, it is a common precursor for preparing graphene. At the same time, graphene oxide is also a new type of carbon material with excellent performance, which has a hig...
