An automated intelligent production method for preparing single-layer graphene

Abstract

The invention belongs to the technical field of preparation of graphene, and relates to an automatic intelligent production method for preparing single-layer graphene. An automatic charging unit automatically charges materials and introduces the charged materials into a reaction kettle unit to react; the reacted materials enter a centrifugal unit for being centrifugally washed, and waste liquor is exhausted by a waste liquor treatment unit; the centrifuged and washed materials enter a drying unit for being dried; the dried materials enter the reaction kettle to continuously react and then re-enter the centrifugal unit for being centrifugally washed, waste liquor is exhausted by the waste liquor treatment unit, and a generated graphene oxide water-phase dispersion liquid is received by a material receiving unit or enters a drying unit for being dried to obtain graphene oxide powder; and finally, obtained single-layer dispersion liquid graphene oxide powder is received by the material receiving unit. The automatic intelligent production method is reasonable in design, reliable in principle, convenient to operate, low in rejection rate and environmentally-friendly.

Description

Technical field: [0001] The invention belongs to the technical field of graphene preparation, and relates to an automatic intelligent production method for preparing single-layer graphene, which is suitable for large-scale production of graphene oxide aqueous phase dispersion liquid, graphene oxide powder and single-layer graphene powder. Background technique: [0002] Graphene is a sheet-like two-dimensional material in which carbon atoms form a hexagonal honeycomb lattice structure with sp2 hybrid orbitals. It is the thinnest and hardest nanomaterial known in the world, and has extraordinary electrical and thermal conductivity. It can be widely used in solar cells, sensors, nanoelectronics, high-performance electronic devices, composite materials, field emission materials, gas sensors and energy storage, etc. Its appearance is expected to trigger a revolution in the field of modern electronic technology. However, graphene's current problems such as low output, high energy...

AI Technical Summary

Problems solved by technology

However, graphene's current problems such as low output, high energy consumption, and poor quality limit its large-scale production and application.

At present, graphene is still in the stage of research and development, pilot test, and small batch production. Industrial production has immature technology and process, and there is no intelligently controlled production line.
