The emerging science of graphene based engineered materials as functional surfaces for mechanics, electronics, sensing and other myriad applications is growing. This chapter brings state of the art graphene based materials to study the structure, preparation, properties, and implications. Derivatives studied in this chapter include graphene, graphene oxide, and reduced graphene oxide. The potential industrial implementation of the graphene synthesis methods is reviewed using the key criteria of cost, process condition, yield, scalability, product quality and environmental impact. In recent years nano graphene and its derivatives are finding their vast applications. Although, the properties are tremendous still there are some limitations as their toxicity is a major issue. Regardless of specific irregularities in various detailed test results and theories of toxicity mechanisms, results infer that the physicochemical properties, for instance, surface functionalities, coatings, charges, and structural imperfections of graphene may influence its in vitro/in vivo conduct just as its toxicity in biological frameworks. Henceforth, toxicity of graphene and its functionalized derivatives as a major issue is also dealt in later part of the chapter. |
