Monolayer graphene is a bi-dimensional material that stands out because of its excellent mechanical properties, its great thermal and electrical conductivities, and presents a high optic transmittance. High quality monolayer graphene that is produced in the laboratory is generated through the Chemical Vapor Deposition technique (CVD) on copper, and then is released by the formation of hydrogen on the surface of the substrate from the hydrolyzation of water.
Maximize the production of the conducting graphene suspensions through this process and obtain a higher performance of the system, is possible using commercial reels through which the graphene is deposed during CVD process and then released with a special equipment design especially for this purpose.
To determine the quality of the graphene generated and perform a study of the quantity of it, characterization techniques such as SEM microscopy, Raman spectroscopy and IR spectroscopy are used. As well, to determine the possible impurities that can appear during the release, the energy dispersive X-ray spectroscopy takes place.
