“…A carbon nanotube (CNT) is one of the revolutionary discoveries in the 20th century. , The exceptional carbon molecular network structure and physical properties like high conductivity, high surface area, and mechanical strength of CNTs have been attracting scientists of different disciplines and researchers to utilize this material for extending its application fields. , Functionalization of CNT is a cutting-edge research topic in the material application field. In general, following methodologies are adopted for functionalization of CNTs: (i) covalent modification, , (ii) self-assembling, (iii) π–π bonding, (iv) encapsulation, , (v) chemical and electrochemical polymerization of organic monomers, , and (vi) nanocomposites. , In all of these modifications, a few monolayer thick target molecules have been adsorbed on the CNT surface.…”
