Graphene is formed by peeling extremely thin layers of graphite off of a larger piece, in the original paper published on graphene it was done using tape.
In the field of nanotechnology, graphene is typically made using a method called chemical vapor deposition. This involves heating a carbon-containing gas, like methane, to high temperatures in a controlled environment, which causes the carbon atoms to form a single layer of graphene on a substrate. The process allows for the precise control of the thickness and quality of the graphene produced.
Graphene has higher conductivity than silver.
Graphene is a single layer of carbon atoms arranged in a hexagonal lattice, known for its exceptional strength and conductivity. Graphene oxide is graphene that has been chemically modified with oxygen-containing functional groups, making it easier to disperse in solvents. Graphene is mainly used in electronics and materials science, while graphene oxide is often used in biomedical applications due to its biocompatibility and water solubility.
It is not recommended to make graphene at home due to the complex and potentially dangerous process involved. Graphene is typically produced using specialized equipment and techniques in a controlled laboratory setting. Attempting to make graphene at home without proper knowledge and equipment can be hazardous.
Graphene is strong because its carbon atoms are arranged in a tightly-packed hexagonal lattice that provides a stable structure. This unique arrangement allows graphene to efficiently distribute and absorb mechanical stress, making it incredibly strong for its size. Additionally, the strong covalent bonds between carbon atoms in graphene contribute to its exceptional mechanical properties.
Graphene does not occur naturally in its pure form; however, it can be found in graphite, which is a natural form of carbon. When graphite is processed or exfoliated, it can produce graphene sheets. Additionally, researchers have discovered graphene-like structures in some natural materials, such as certain types of carbon-rich minerals or in soot. Overall, while graphene itself is synthesized for various applications, its parent material, graphite, is found naturally.
Graphene is a single layer of carbon atoms arranged in a two-dimensional honeycomb lattice, making it just one atom thick. This unique structure gives graphene its remarkable electrical, thermal, and mechanical properties. When multiple layers of graphene are stacked together, they form graphite, but each individual layer remains only one atom thick.

Graphene, graphite, and some carbon nanotubes can all conduct electricity.
Graphene is pretty amazing. An adequate description of the properties is rather long. There is a link below to the properties section of an article on graphene.
A graphene filter is a type of filter that uses graphene-based materials to capture and remove impurities from a fluid or gas. Graphene's unique properties, such as its high surface area and strength, make it an effective filtration material for applications like water purification, air filtration, and gas separation. Graphene filters are known for their efficiency, durability, and ability to remove even small particles or contaminants.

Graphene is a material that can exhibit both insulating and conducting properties. In its pristine form, graphene is a highly efficient conductor due to its unique 2D structure. However, by introducing defects or doping, graphene can also exhibit insulating behavior, making it a versatile material for various electronic applications.

Graphene is a very thin layer of graphite. It is so thin, it is so close to being invisible!
While it is technically possible to extract graphene from pencils using a process called exfoliation, it is not very efficient or practical for producing high-quality graphene. Laboratory techniques and equipment are typically used to produce graphene on a larger scale for commercial applications.
