Description

technical field

[0001] The invention relates to the technical field of two-dimensional material preparation, in particular to a device and method for producing graphene by an electric shock method. Background technique

[0002] Graphene is a two-dimensional material composed of a honeycomb combination of carbon atoms. It has excellent mechanical, thermal, optical, electrical and other properties and has a wide range of uses. It has been widely used in mobile phone cooling, improving concrete strength, flexible displays, super Capacitors and other fields. Because of its broad market space, many chemical companies have also introduced graphene products produced by different methods, such as mechanical exfoliation, liquid phase exfoliation, and redox methods.

[0003] However, these methods are still restricted by cost, quality, and efficiency factors, such as mechanical stripping method, which has low efficiency; liquid phase stripping method, which has low quality and effici...
