Problems solved by technology

While ensuring the flatness of the growth substrate surface, it is also necessary to avoid deformation of metal substrates due to mutual contact and adhesion when preparing graphene films, so the amount of graphene prepared in a single time is limited
Although South Korea's Sungkyunkwan University can prepare a graphene film with a diagonal of 15 inches at a time, it uses a tube furnace with a diameter of 8 inches and covers the inner wall of the entire furnace tube with the graphene growth substrate, leaving the rest of the growth space It has not been rationally utilized, not only the number of single-growth batches prepared is small, but also causes waste of resources
Recently, Japan’s Sony has achieved roll-to-roll growth of graphene by heating the growth substrate with electrodes. However, due to local heating and low temperatu

Abstract

The invention relates to a clamp for preparing graphene and a method for preparing graphene. The clamp comprises a horizontal top frame, a bottom frame and a loading tray, wherein the top frame and the bottom frame are fixedly connected through a first side plate, a second side plate and a baffle plate, which are vertically arranged; both the top frame and the bottom frame are of plane structures with openings in the middle parts; the top frame, the bottom frame, the first side plate, the second side plate and the baffle plate form a quad structure with an opening in one side surface; the first side plate and the second side plate are oppositely arranged in parallel; a plurality of tray grooves are uniformly formed in both the first side plate and the second side plate; two opposite side edges of the loading tray are respectively inserted in the tray grooves. The clamp reasonably utilizes the limited growth space in a process cavity, so that the quantity of the graphene thin films prepared in one batch is increased to the greatest extent to realize the minimization of the resource waste and the maximization of the cost while ensuring the quality of the prepared graphene thin films.

Description

technical field [0001] The invention relates to the technical field of graphene preparation, in particular to a jig for preparing graphene and a method for preparing graphene. Background technique [0002] Graphene is a single atomic layer two-dimensional planar film composed of carbon atoms with sp2 hybrid orbitals to form a hexagonal honeycomb lattice structure. In 2004, physicists Andre Geim (Andre Geim) and Konstantin Novoselov (Konstantin Novoselov) of the University of Manchester successfully separated graphene from graphite in experiments, the first time Prove that single atomic layer 2D materials can exist independently. Graphene has excellent mechanical, thermal, optical, electrical and other properties, and has been extensively studied within a few years of its discovery. The scientists who discovered graphene, Andre Geim and Konstantin Novoselov, also won the 2010 Nobel Prize in Physics for their pioneering work on graphene. Graphene has broad application prosp...
