There are several methods to produce graphene films. The most common techniques include:
Chemical Vapor Deposition (CVD): This method involves decomposing a carbon-containing gas on a substrate, resulting in a graphene film. It is widely used for producing high-quality graphene on a large scale. Mechanical Exfoliation: This involves peeling layers from bulk graphite to produce graphene flakes. Though simple, it is not suitable for large-scale production. Liquid-phase Exfoliation: This method disperses graphite in a liquid medium, followed by sonication to produce graphene. It is scalable and suitable for various applications.
