“…These results were explained by changes in the crystalline structure of polymers due to the introduction of fullerene. 57 This conclusion was proved by the direct electron microscopy observations; the corresponding microscopic images clearly demonstrate that the dimensions of the crystalline grains are reduced and the inter-crystalline regions are narrow and diffuse. According to the authors' view, fullerene molecules can serve as nucleation sites for crystallization and, thus, can regulate the degree of crystallinity in polymers.…”

“…One can see the effect of fullerene (0.01-0.02 wt%) on the main characteristics of Caprolon from the data, given in Table 2. 57 As compared to the reference samples, nanocomposites are characterized by higher compressive strength (this value increases by 25%) and Brinell hardness (by 7%). This effect is similar to that provided by the introduction of metals; however, the content of fullerene is one to three orders of magnitude lower than that of metals.…”

“…At the same time, accounting for the solubility of fullerenes in aromatic hydrocarbons, the possibility to use fullerenes or products containing them as sorbents is rather doubtful. Additives of fullerenes and fullerene soot improve mechanical, physical, chemical, and electrical properties of caprolon [46]. Tribological characteristics of Fluoroplast-4 increased by adding to it fullerene soot and fullerene black [47].…”

This review concerns the fullerene black, a poorly known nano-sized carbon material, the insoluble residue after extraction of fullerenes from fullerene soot produced by arc evaporation of carbon material (usually graphite) in a helium atmosphere. This by-product of the production of fullerenes, whose yield reaches 80 wt %, is a finely dispersed material with a particle size of 40-50 nm. It includes amorphous carbon, graphitized particles, and graphite. Test reactions showed the presence in the structure of fullerene black of curved surfaces, and, like fullerenes, of alternating non-conjugated simple and double bonds. In addition to the double bonds, its structure includes dangling bonds in the concentration not higher than one per 1200 carbon atoms. This nano-carbon can not be graphitized, enters into the reactions of nucleophilic addition, and absorbs oxygen and water from the atmosphere. The fullerene black as was shown activate hydrogen and thus to undergoes to a hydrogenolysis without a catalyst and to catalyzes the dehydrogenation and dehydrocyclization of alkanes. This carbon nanomaterial can be used as a sorbent for organics, as a catalyst support, as a tribotechnical additive; and it can interact with carbide-forming metals and reinforces their surface.

“…The polymerization mechanism was suggested in [5], and a correlation between the concentration of pure ë 60 fullerene in polystyrene, polymerization temperature, and polymerization yield was established. According to [6], fullerenes and fulleroid materials very strongly influence the polymerization of various organic compounds and radically change the properties of polymers (mechanical, physicochemical, and electric). For example, it was shown [6] that the samples of caprolone modified by pure fullerenes and a mixture of fullerenes showed improved hardness, impact toughness, attrition resistance, softening and melting temperatures, moisture absorption, and moisture capacity.…”

The modification of samples allows the electrophysical characteristics of caprolones (specific volume resistance, dielectric resistance, and tangents of dielectric losses) to be varied to a substantial extent.…”
