Yes, it is possible to mechanically "squeeze" graphite into graphene through a process called mechanical exfoliation or the Scotch tape method. This method was actually used by Andre Geim and Konstantin Novoselov, who won the Nobel Prize in Physics in 2010 for their work on graphene.
The process involves taking a piece of graphite, which is made up of layers of graphene stacked on top of each other, and repeatedly peeling off layers of graphene using adhesive tape. By applying the tape to the graphite and then peeling it off, some layers of graphene are separated and transferred onto the tape. This process is repeated multiple times, leading to further thinning and isolation of individual graphene layers.
While the Scotch tape method is effective for producing small quantities of graphene, it is not suitable for large-scale production. Other methods such as chemical vapor deposition (CVD) and epitaxial growth on silicon carbide are used to produce graphene on a larger scale. These methods involve the deposition of carbon atoms onto a substrate under controlled conditions, allowing for the synthesis of high-quality graphene films.
