Graphene mass production equipment and manufacturing method thereof

Abstract

The invention provides graphene mass production equipment and a manufacturing method thereof. The manufacturing method comprises the steps of (1) arranging a first electrode and a second electrode in electrolyte of an electrolytic cell, wherein the first electrode is a positive pole, the second electrode is a negative pole, the first electrode is arranged in a roller provided with a screen, and the roller is internally provided with a plurality of graphite fragments; (2) applying first bias voltage, enabling the roller to roll under the first bias voltage, and carrying out ion embedding on the graphite fragments; (3) continuously applying second bias voltage in the rolling process of the roller, and carrying out layer dismounting and stripping on the graphite fragments; (4) after the graphite fragments are subjected to layer dismounting and stripping, forming at least one layer of graphene fragments; (5) depositing the graphene fragments onto the bottom of the electrolytic cell by means of the screen of the roller. Therefore, the method overcomes the defects of an existing electrochemical stripping method for manufacturing graphene, can realize mass production, and is convenient for collection and use of graphene, thus obtaining excellent economic benefit of graphene manufacturing.

Description

technical field [0001] The invention relates to a mass production technology of graphene, in particular to a graphene mass production equipment and a manufacturing method thereof which can produce graphene in large quantities by electrochemical means and facilitate the collection and acquisition of graphene finished products. Background technique [0002] Graphite is a crystalline structure composed of multiple layers of graphene, and graphene is a single-layer graphite structure with sp between each carbon atom 2 The crystalline structure forms bonds with three adjacent carbon atoms and extends into a two-dimensional honeycomb hexagonal structure. At present, graphene has been widely used in the fields of semiconductors, touch panels or solar cells, and it is more expected It is widely used in the development of many industrial fields such as optoelectronics, green energy power generation, environmental biomedical sensing, and composite functional materials.
