Abstract

The invention relates to an experimental detection device and method for preparing graphene by a laser. The device comprises a movable platform, a reaction vessel is arranged on the movable platform and integrally positioned in a heating cover, a powered-on electrode and a large electrode block are arranged in the reaction vessel, the powered-on electrode is connected with a voltage controller, the large electrode block is connected with a double-electric-logging four-probe tester, and a laser generation system is arranged on the upper portion of the reaction vessel. According to the device, laser-shocked plasmas can sufficiently contact with an electrode base and are deposited on the electrode base. The temperature of water in the reaction vessel is gradually increased by the heating cover, and generation experiments of the graphene are detected in real time, so that optimal temperature suitable for preparing the graphene is acquired.

Description

technical field [0001] The invention belongs to the technical field of artificially preparing graphene. Background technique [0002] Graphene has unique physical and chemical properties. However, tiny graphene cannot really exert its superior properties. Therefore, research on the preparation of large-size and high-efficiency graphene is necessary. Since the advent of graphene in 2004, how to efficiently prepare it has attracted the close attention of researchers, and theories and methods for preparing graphene have emerged in an endless stream. In addition to the traditional mechanical exfoliation and redox methods, there are also chemical vapor deposition and epitaxial growth methods that were widely used later. At present, laser-induced graphene preparation technology has also become a research hotspot. [0003] At present, the research on the devices and methods of laser shocking carbon materials in liquid media to prepare graphene is increasing, but few people pay att...
