Abstract: Carbon nanomaterials have always been an area of interest for their applications in all the fields of science starting from materials science to biology. The current research is focused on low cost and simple methodologies to prepare functional carbon nanostructures from carbon rich precursors. Towards this goal, carbon nanofibers were isolated from soot and employed as an adsorbent for the removal of amines from waste water. Besides, various solution phase methods for the production of processable graphene nanosheets directly from graphite were explored. This has been achieved by both non-covalent stabilization and covalent functionalization of exfoliated graphene sheets. Covalent functionalizations enable the incorporation of various functional moieties onto graphene. The applicability of these functionalized graphene sheets in polymer composites and metal hybrids were systematically investigated. Incorporation of graphene improves the mechanical and thermal stability of the composites, along with an increase in the electrical conductance
