Equipment for quickly preparing graphene and preparation method of graphene

Abstract

The invention discloses equipment for quickly preparing graphene and a preparation method of graphene. The equipment comprises a pipe furnace, a sample loading cabin, a vacuum valve and a plurality of sample loading boats, wherein the pipe furnace comprises a quartz pipe, one end of the quartz pipe is the heating end, the other end of the quartz pipe is connected with the sample loading cabin through the vacuum valve, and a heating device is arranged at the outer part of the heating end of the quartz pipe; a first air inlet and a first air outlet are formed in the quartz pipe of the pipe furnace; a second air inlet, a second air outlet and a sample loading opening are formed in the sample loading cabin; a position-changing device and a shifting device are arranged in the sample loading cabin; the sample loading boats are arranged above the position-changing device of the sample loading cabin; the relative positions of the sample loading boats and the shifting device are changed through the position-changing device; the shifting device drives the sample loading boat corresponding to the shifting device in position to move between the shifting device and the heating end of the quartz pipe. According to the invention, the growth efficiency of the pipe furnace is greatly improved, and the energy loss and waste are reduced.

Description

technical field [0001] The invention relates to a device for rapidly preparing graphene and a preparation method thereof. Background technique [0002] Graphene is a flat film composed of carbon atoms with sp2 hybrid orbitals forming a hexagonal honeycomb lattice. It is a new two-dimensional material with only one layer of carbon atom thickness. Due to the special chemical structure of graphene, it has very excellent properties in mechanics, heat, optics, electricity, etc., such as super-strong electrical conductivity, wide-spectrum high transparency, ultra-high mechanical strength and good thermal conductivity . The unique physical properties of graphene determine its broad application prospects. For example, graphene is widely used in optoelectronic devices and can be used to make flexible transparent electrodes. Flexible transparent electrodes made of graphene are compatible with the current market-leading ITO transparent electrodes. Ratio, stronger light transmittance,...

Problems solved by technology

This device improves the production efficiency to a certain extent, but a large amount of heat will be lost during the moving process. After re-injection, it will take a while to return to the deposition temperature, which indirectly prolongs the growth cycle.
