Optical and Electrical Properties of Polymer Nanocomposite Dielectric Based on Polyvinyl Alcohol and Fullerenol C60(OH)44

The optical and electrical properties of PVA films and PVA + C6o(OH)44 nanocomposite have been compared. It was found that even a small addition of fullerenol molecules to PVA leads to its coloration, and the nanocomposite films become opaque in the UV region of the spectrum. It is shown that at ele...

Description
Summary:The optical and electrical properties of PVA films and PVA + C6o(OH)44 nanocomposite have been compared. It was found that even a small addition of fullerenol molecules to PVA leads to its coloration, and the nanocomposite films become opaque in the UV region of the spectrum. It is shown that at elevated temperatures, noticeable differences in the conductivity and low-frequency dielectric permittivity of PVA films and PVA+fullerenol composite films are observed. Their possible causes are analyzed.
