Effect of Polystyrene/Fullerene Composites on the Lipid Peroxidation in Blood Serum

“…We have chosen polystyrene (Aldrich, Germany, М n = 1.4•10 5 , M w /M n = 1.64) as a matrix for fabrication of fullerene-containing nanocomposites, because it has high solubility in aromatic hydrocarbons like fullerene itself. C 60 +C 70 fullerene mix (Fullerene Technologies Ltd., Russia) was preliminary purified [17].…”

Electrooptical and Molecular Properties of Fullerene-Containing Poly(Methyl Methacrylates) Prepared by Introducing Fullerenes C60 and C70 into the Polymer Structure by Different Methods

“…1 wt %. At the same time, when C 60 is introduced into PVP by complexing, there are no such changes [8].…”

“…This makes it possible, first, to exploit the properties of fullerenes spread in thin polymer films and, second, to usefully modify the polymer support itself, e.g., to increase its electrical conductivity [5] or to impart to it nonlinear optical properties [6]. Our previous studies of C 60 derivatives [7,8] and published data on hybrid polymeric compounds with various types of chemical bonding of fullerenes [13 6, 9] suggest that the outcome of modification of the polymer depends on the method of introducing fullerene into its composition. Even relatively small weight fractions of fullerenes in some cases significantly affect the initial polymer.…”

“…To this end, we carried out viscometric studies of the polymer solutions in benzene, determined their molecular weights M, and studied their electrooptical properties by the method of the Kerr effect in a pulsed electric field [12]. We chose the Kerr effect for this study, since it is highly sensitive to any changes due to structural transformations in the polymer chain, as well as ÄÄÄÄÄÄÄÄÁÄÄÄÄÄÄÄÄÄÄÄÁÄÄÄÄÄÄÄÄÄÄÄÁÄÄÄÄÄÄÄÄÄÄÄÄÁÄÄÄÄÄÄÄÄÁÄÄÄÄÄÄÄÄÄÄÄÄÄÄÁÄÄÄÄÄÄÄÄÄÄÄÄÄÄ since it already demonstrated its suitability for detecting the changes in the properties of fullerene-containing compounds relative to the initial analogs [7,8].…”
