Abstract

The invention relates to a device for preparation of graphene with lead wires. The device includes a container, a first lead wire fixation plate, a second lead wire fixation plate, a weak acid electrolyte solution, a power supply, a metal mesh electrode and several lead wires. The second lead wire fixation plate is embedded at the bottom of the container, the container is filled with the weak acidelectrolyte solution, and several lead wires are vertically welded on the inner surfaces of the first lead wire fixation plate and the second lead wire fixation plate. The invention mainly utilizes the principle of electrolysis, through constant electrolysis of the metal mesh electrode to expanded graphite worms, the expanded graphite worms are peeled layer by layer in the electrolyte solution, and then through constant electrolysis of the lead wires, full electrolytic stripping is carried out on the expanded graphite worms, and at the end of electrolysis, cleaning, filtering and drying are conducted so as to obtain the needed graphene.

Description

technical field [0001] The invention belongs to the technical field of graphene preparation, and in particular relates to a device and method for preparing graphene by using lead wire. Background technique [0002] Graphene is a two-dimensional crystal composed of carbon atoms exfoliated from natural graphite material. Graphene is both the thinnest material and the strongest, with a breaking strength 200 times stronger than the best steel. At the same time, it has good elasticity, and the stretching range can reach 20% of its own size. It is currently the thinnest and strongest material in nature. The most potential application of graphene at present is to become a substitute for silicon, to manufacture ultra-miniature transistors, and to produce future supercomputers. Replace silicon with graphene, and computer processors could run hundreds of times faster. Plus, graphene is almost completely transparent, absorbing only 2.3 percent of light. On the other hand, it is so ...
