After such a long period of defining the properties of graphene, attention is shifting to its manufacturing process to make it more effective, efficient, and cost-effective. Graphene has been considered as an astonishing material that is set to transform each individual’s daily living; however, the production of graphene production has always been too costly until today.
Among one of the obstacles that nanomaterials face when it comes to achieving their goals of impact is the manufacturing process with a specific cost that will make them competitive with the intended materials to be replaced. In the year 2010, it used to cost around thousands of dollars just to produce a piece of graphene that is sized smaller than a postal stamp. Ever since that moment, there had been numerous yet arduous methods such as synthesizing graphene in furnaces with very high temperatures, or splintering off pieces of these from graphite has actually given way to large-scale, room temperature processes that promise to be cheaper compared to the previous procedures.
Listed here are some means on how to lower the production cost of high-quality graphene:
CVD Techniques – Polycrystalline Graphene
One of the greatest goals has always been to search for various ways to create graphene in bulk or large quantities while at the same time, producing quality-made polycrystalline single layers of graphene. Late during the previous year, a company disclosed funding from the NSF or National Science Foundation, to come up with a new technique for producing and manufacturing graphene in a roll to roll process; this company’s technique is a combination of CVD or Chemical Vapor Deposition.
These types of techniques have different types of forms but are generally chemical processes where solid materials that are present in a gaseous form is sprayed on copper (which is the substrate in this case). Once solid materials in their gaseous state come into contact with heated substrates in a reaction chamber or a furnace, the gaseous materials transform into their solid form and are then transferred onto the substrate; when it comes to graphene production, the outcome of the process of CVD is a graphene film that lies at the top of nickel or copper.
Produce Graphene by the Use of Copper
The process of producing graphene is generally known as chemical vapor deposition which works by altering gaseous reactants into a graphene film that can be found on a special surface called substrate. At Glasgow, their research team have used an identical process but instead, used commercially present copper foil as a surface where they could create graphene that was of high-quality. The copper foil is commonly used as negative electrodes found in lithium-ion batteries. Furthermore, researchers have realized that the copper surface used provides an exceptional bed where the graphene can form.
The graphene production technique of the university’s research team has not only successfully lowered the cost of production, but they have also offered absolute improvement in the optical and electrical performance of graphene compared to the older and much costly process. The new approach to CVD drastically lowers the graphene pricewhile also improving specific elements of the effectiveness of graphene.
It is no doubt that graphene is one of the stars when it comes to the field of nanotechnology in this time and age; its unique fusion of amazing properties plus a host of potential applications for commercial uses have grabbed the interest of engineers and scientists all over the world. Moreover, potential graphene applications are continuously growing which may be put to use in extremely light cables for space elevators in the future.
