“…The above data suggest that the highest amine content is obtained in the case of BP-ODA, and the lowest amine content is observed for BP-DAN, which is in agreement with our previous results on a comparatively low reactivity of DAN in the gas-phase functionalization of fullerene C 60 and pristine MWCNTs [26].…”

“…The existence of amine molecules physically adsorbed on CNTs in addition to the covalently-bonded ones is quite natural and was already documented and discussed previously [12,14,15,18,26]. Pristine CVD-grown MWCNTs have closed ends and tend not to adsorb [12,15,26] or adsorb very small amounts (of a few wt%) [14] of amines under the functionalization conditions employed.…”

“…The observed high stability can be explained, on one hand, by increasing BP water-repelling properties, and on the other hand, by stronger sticking between individual MWCNTs, both effects being due to the introduction of hydrocarbon substituents into the nanotube structure. An additional stabilizing factor in the case of BP-DAN might be the covalent cross-linking of neighbor CNTs with functionalizing diamine molecules [14,15,26]. additionally, the band at 719 cm -1 can be due to methyl rocking vibrations in octadecyl radicals.…”

“…Pristine CVD-grown MWCNTs have closed ends and tend not to adsorb [12,15,26] or adsorb very small amounts (of a few wt%) [14] of amines under the functionalization conditions employed. However, the situation changes when CNTs have open ends allowing for endohedral adsorption: in this case, the amount of physisorbed amine can be comparable or even much higher than that of covalently attached moieties [18].…”

“…In principle, a vast variety of amines can be employed, with the condition of their sufficient thermal stability and volatility under reduced pressure. The functionalization of pristine BP samples was performed under the general conditions described in our recent report on the solvent-free functionalization of pristine MWCNTs with aromatic amines [26]. (However, the chemistry of defect-containing pristine MWCNTs is different from the chemistry of BP composed of acid-oxidized nanotubes.)…”

Functionalized fullerene nanostructures are a distinct class of materials that exhibit the combined properties of both fullerene and nanostructures including excellent optoelectronic features, modified band edges, high electron affinity, fast charge transfer capabilities, and tunable structural and textural properties. These fascinating properties allow for their utilization in many applications such as polymer solar cells, photovoltaics, photocatalysis, photodynamic therapy, electrocatalysis, environmental remediation, and drug and gene delivery. Numerous synthesis methods and anchoring groups are employed for functionalized fullerenes with nanostructures by using convergent bottom-up and top-down strategies. The supramolecular self-assembly and functionalization of fullerenes through robust chemistry approaches such as surface oxidation, grafting, polymer coating, doping of metals/nonmetal heteroatoms, noncovalent modification with 2D materials and nanoparticle attachment result in achieving fine control over its surface and bulk properties, including increased solubility, wettability, electron transport, acid-base properties, adsorption, electronic conductivity, and light absorption. This review analyzes the salient developments in the fabrication of nanostructured fullerenes and their functionalized derivatives for many applications including adsorption, catalysis, sensors, energy storage, solar cells, drug delivery, magnetic and superconducting devices. The contents of this review will allow the readers to cherish exciting possibilities and opportunities in field of functionalized nanofullerenes.

In this study, the effect of diamine molecular structure, attached to the multiwalled carbon nanotubes (MWCNTs), on the interfacial interactions of the MWCNTs and the epoxy matrix was studied. Pristine MWCNTs were successfully functionalized with multiple aliphatic and aromatic diamines. It has been found that, compared to aliphatic molecules, aromatic diamines can yield higher functionalization degree, due to higher activity and longer half-life of aromatic intermediates. However, at the same functionalization degree, the aliphatic ligands were more successful in reacting with epoxy chains and forming covalent bonds between the MWCNTs and the matrix. Considerable improvements were achieved in the mechanical properties of functionalized MWCNT-reinforced epoxy composites in comparison with the pristine MWCNT-reinforced composites. Fractography observations revealed distinct differences in the failure modes of reinforced composites after functionalization of the MWCNTs with diamines. POLYM. ENG.
