ABSTRACT
This chapter provides an overview of spectroscopic and microscopic responses of graphene/CNT nanocomposites. Carbon is a most common element in the world, which is the 15th abundant element in the crust of the Earth and is the fourth most common element in the universe, with respect to mass, next to helium, hydrogen and oxygen. In 2004, Novoselov and Geim fortunately isolated and analyzed a monolayer of graphene (MLG), which has led the scientists to elucidate the insights and the possibilities for altering the structure and properties of graphene and its other forms for desired applications. Since, the scientific breakthrough of graphene discovery, several physical and chemical approaches are reported for its synthesis to evaluate and demonstrate their industrial applications. Micromechanical exfoliation or scotch-tape approach was the first and an oldest physical approach for the synthesis of MLG on the surface of selected substrates.
