    Abstract:

    Carbon materials that include diamond, graphite, graphene, carbon nanotubes (CNTs), among them CNTs
    have received considerable attention from many researchers due to their extraordinary mechanical,
    electrical, and thermal properties. These excellent properties provide thrilling opportunities to fabricate new
    materials for advanced applications. Owing to their outstanding properties, scientists are interested to
    investigate and modify these new substance classes. However, they are available in the form of fluffy powder,
    which is difficult to handle. In addition, as grown carbon materials contain a large amount of impurities such
    as growth metal catalyst (Fe, Ni, and Cu), particle soot, and amorphous carbon as a synthetic
    residue. The well homogeneous dispersion of these materials into the host media, which can be in the form
    of liquid or solid materials, is one of the major challenges encountered in the fabrication of nanocomposite
    and devices used in nanoelectronic and interconnected technologies. Also, these materials are chemically
    inert and have poor solubility in solvents as well as in water because of the strong carbon –carbon
    interaction and van der Waals’ attractions between them. This limitation often requires controlled chemical modification/functionalization of these materials on the surface of the carbon materials in order to improve their solubility and dispersion stability in the solvent including water. Chemical functionalization has
    been simply dispersed and solubilizes these carbon materials, by attaching hydrophilic species to their hydrophobic structures. In spite of this, functionalization process removes impurities like amorphous/carbonaceous carbon and dissolution of the metal catalyst although aggressive functionalization of
    carbon materials shortens its length and destructs their structure, which strongly affect the electrical properties. These functionalized materials are proving to be valuable in a broad range of areas starting from the preparation of nanocomposites to the fabrication of sensors, solar cell and lithium ion battery.
