Graphene is an allotrope of carbon that exists as a two-dimensional planar sheet. Graphene is technically a non-metal but is often referred to as a quasi-metal due to its properties being like that of a semi-conducting metal. As such, Graphene has many unique properties that cannot be found with other non-metallic materials.
In Graphene the carbon–carbon bond length is about 0.142 nanometers. Graphene sheets stack to form graphite with an interplanar spacing of 0.335 nm.
Graphene is the strongest material ever tested in the world, with an intrinsic tensile strength of 130.5 GPa and a Young's modulus of 1 TPa (150000000 psi). In addition to having a unique strength, Graphene is also very lightweight (0.77 mgm-2).
Of course with these strong mechanical properties, Graphene is one of the most important chemicals that is researched. Let's look at some studies doing by taking into account of Graphene's extraordinary properties.
The adhesion energy of Graphene with substrate is an important mechanical property for the wafer- level production of micro- and nano-devices because high adhesion ensures manufacturability and stability of operation over a long period.
Over the last decade, many solid lubricant materials and surface treatment processes have been developed for efficient operation and extended lifetime in MEMS/NEMS applications, and for various fabrication processes such as nanoimprint lithography and transfer printing. One of the important considerations in applying a solid lubricant at the micro- and nanoscale is the thickness of the lubricant and the compatibility of the lubricant deposition process with the target product. Graphene, is a good candidate for these applications with its atomically thin and strong structure with low surface energy.
Coating objects with Graphene can serve different purposed. For instance, researchers have now shown that it is possible to use graphene sheets to create a superhydrophobic coating material that shows stable superhydrophobicity under both static as well as dynamic conditions, thereby forming extremely water repelling structures.
Researchers say that Graphene is the world's thinnest known coating for protecting metals against corrosion. It was found that graphene, whether made directly on copper or nickel or transferred onto another metal, provides protection against corrosion.
