Graphene has changed the game in the field of innovative materials due to its remarkable qualities. Chemical vapor deposition (CVD) has drawn a lot of interest in the different ways to make graphene. For a wide range of uses, including composite materials, electronics, and optoelectronics, CVD graphene offers enormous promise.
What is CVD Graphene?
CVD graphene refers to graphene synthesized through the chemical vapor deposition process. It entails the deposition of carbon atoms onto a substrate to create a layer of graphene. The fabrication of high-quality, large-scale graphene films is possible with the CVD process, making it appropriate for industrial uses.
What is the production process of CVD Graphene?
There are various steps in the production process. A substrate is initially heated to a certain temperature in a controlled environment. Substrates are often comprised of copper or nickel. The introduction of a carbon-containing gas—such as methane or ethylene—causes the gas’s carbon atoms to interact with the heated substrate surface.
