Onion-like-carbon-based composite films: Theoretical modeling of electromagnetic response

Polarizability as a landmark property for fullerene chemistry and materials science

“…Indeed, analysis of periodicals shows that studies on endofullerenes started with theoretical treatment of Sc n @C m polarizabilities in Torrens's works. [199][200][201] In 2007, a monopoledipole interaction approach was applied to study dielectric properties of giant multi-shell carbon nano-onions [202][203][204] and then double-shell C 60 @C 240 nano-onion was studied by DFT in Zope's work. 48 Later, polarizabilities of endofullerenes with encapsulated noble gas atoms, [205][206][207] simple molecules (H 2 O or CH 4 ), 55,208,209 and relatively large hydrocarbons (norbornadiene and quadricyclane) 57 were calculated.…”

“…The described nonadditivities are typical for the other fullerenes and more complex encapsulated molecules (e.g., in the case of the fullerenes C 70 , C 80 , C 90 , C 100 , and C 120 with the trapped quadricyclane and norbornadiene molecules 57 ). The most complex objects, for which depression of polarizability has been postulated, are C 60 @C 240 endofullerene (studied by DFT 48 ) and multi-shell carbon nano-onions (e.g., 2(C 540 @C 960 ) @C 2910 , studied in terms of monopole-dipole interaction approach [202][203][204] ). For C 60 @C 240 , depression of polarizability and screening coefficient equal to À74.1 Å3 and 0.90, respectively (PBE/NRLMOL calculations 48 ).…”

Graphite oxide as a carbocatalyst for the preparation of fullerene-reinforced polyester and polyamide nanocomposites

“…To the best of our knowledge, GO has never before been used as a precursor to multiwalled fullerenes, which are typically prepared by exposing graphite or other graphitic precursors (e.g., C 60 ) to an arc discharge under water. 51 Multiwalled fullerene-based polymer composites have been shown to exhibit intriguing properties, such as strong dielectric response in the microwave frequency range, 52,53 though the difficulties associated with the preparation of layered fullerenes on a large scale challenges broader study. As a result of the efficient dispersion of the carbon in the present PCL matrix, the mechanical properties of the polymer were significantly enhanced upon incorporation of the filler, as described previously.…”

Recent progress in the preparation and application of carbon nanocapsules

“…In addition to the catalytic properties, the electromagnetic (EM) shielding abilities of OLCs were also examined [107][108][109][110]. It was found that OLCs can absorb EM waves in a very wide range, not only in the gigahertz (2-38 GHz) region, but also in the terahertz (12-230 THz) region, and can be considered as a new class of broadband EM wave absorbing materials (EMAMs).…”
