ABSTRACT
This article is focused on oxidation and halogenation of fullerene, identification of the prepared products and their potential application. The Fourier transform infrared (FTIR) spectrometry was used for analysis of oxidized fullerene derivative and material balance and elemental analysis were used to identify the summary composition of the prepared fullerene halogen derivatives. We has conformed yet the radioprotective ability of oxidized fullerene in our recently published work radioprotective properties and toxicity test of C60 fullerene derivative in vivo & in vitro. Since radioprotective properties are associated with the ability to recapture free radicals in the system (formed due to radiolysis of water in the physiological environment), this property is closely connected also with fire-retarder properties, when the fire is also a radical mechanism. We tested thermal properties of polyvinyl alcohol (hereinafter PVA) nanofibers prepared with C60 and its derivatives as nanocomposites. The TG-DTA and TG-DSC analysis were used for this purpose. We have demonstrated experimentally that a retarder on C60oxi basis and C60 halogenderivative has good results in increasing of thermal resistance of PVA-based nanofibers.
