Graphene is an incredibly strong and conductive material that has fascinated scientists for decades. Despite its incredible properties, there is still much debate about exactly how much force it takes to break one unit of graphene.

One of the key factors in determining the strength of a material is its atomic structure. Graphene is composed of two layers of carbon atoms arranged in a hexagonal lattice. Each carbon atom is bonded to four neighboring atoms, giving it a total of six bonds. This unique arrangement creates a very strong intermolecular interaction between the atoms, which makes graphene extremely resistant to deformation or fracture.
Despite this strength, graphene is still relatively weak under certain types of stress. For example, when subjected to tensile forces, graphene can crack or split at relatively small strains. However, this strength increases significantly when subjected to compressive forces. When faced with compression, the individual atoms in each layer will vibrate in unison to try and absorb the energy from the applied force. As a result, the overall strength of the material increases as well.
There have been many experiments conducted to determine the strength of graphene under different types of stress. One notable study published in the Journal of Applied Physics in 2013 used a laser-induced breakdown of graphene to measure its strength. The researchers found that under even moderate compression, graphene remained intact for up to several hours without cracking or breaking.
Another important factor in determining the strength of graphene is its thermal stability. While graphene can withstand high temperatures, it becomes fragile when exposed to sudden changes in temperature. For example, if a graphene sheet is placed on a hot surface, it may become deformed slightly before cracking or breaking completely.

Overall, while graphene is a incredibly strong and conductive material, it is not as robust as some other materials that may be subject to more significant forms of stress. The strength of graphene varies depending on the type of stress it is subjected to, but it remains a promising material for use in a wide range of applications, including electronics, sensors, and biotechnology.
