Abstract

The invention provides two-dimensional material transfer equipment, and relates to the technical field of two-dimensional materials, and the two-dimensional material transfer equipment comprises a feeding device, a hot pressing device, a separating device, a cleaning device, a drying device and a receiving device. Through the characteristic that the two-dimensional material can be separated from the metal film through the separation device, the two-dimensional material which originally grows on the metal film is transferred to a target film, the target film to which the two-dimensional material is attached is cleaned and dried so that the target film can meet the collection requirement, an automatic production line for transferring the two-dimensional material can be formed through discharging, hot pressing, separating, cleaning, drying and collecting, therefore, the efficiency and the productivity are improved, meanwhile, the production cost can be reduced, and the occupied area of equipment is saved.

Description

technical field [0001] The present invention relates to the technical field of two-dimensional materials, in particular to a two-dimensional material transfer device. Background technique [0002] With the research boom caused by the discovery of graphene, a large number of new two-dimensional materials (including but not limited to graphene, hexagonal boron nitride (h-BN), transition metal dichalcogenides (TMDs)) can be obtained through chemical Manufactured by vapor deposition (CVD) technology. Since the prerequisite for the application of two-dimensional materials is often to transfer the two-dimensional materials first and then use them, how to transfer two-dimensional materials on a large scale is the focus of attention in the industry. [0003] The existing two-dimensional material transfer methods often can only realize single-sided manual transfer of two-dimensional materials, and the transfer efficiency is low. Contents of the invention [0004] The purpose of t...
