Graphene is an atomic-scale honeycomb lattice made of carbon atoms. Graphene is undoubtedly emerging as one of the most promising nanomaterial because of its unique combination of superb properties, which opens a way for its exploitation in a wide spectrum of applications ranging from electronics to optics, sensors, and biodevices.
For instance, graphene-based nanomaterials have many promising applications in energy-related areas. Just some recent examples: Graphene improves both energy capacity and charge rate in rechargeable batteries; activated graphene makes superior supercapacitors for energy storage; graphene electrodes may lead to a promising approach for making solar cells that are inexpensive, lightweight and flexible; and multifunctional graphene mats are promising substrates for catalytic systems (read more).
An increasing number of companies is involved in commercializing graphene on an industrial scale although the high cost of graphene is one of the major obstacles to its widespread adoption for commercial applications. One of our Nanowerk Spotlights ("Mass production of high quality graphene: An analysis of worldwide patents") has carried out an extensive survey and analysis of global patents pertaining to the various processes of graphene synthesis. The article summarizes the current status of the conventional approaches for the synthesis of graphene based on the survey of literature.
