NANOCOMPOSITES BASED ON SILICA AND WATER- SOLUBLE DERIVATIVES OF FULLERENE C60
A method for synthesis of nanocomposites based on aminated aerosilogel and watersoluble derivatives of fullerene C60 (fullerene C60-trismalonyl, fullerene C60- hydrox yproline, fullerene C60-threonine, fullerene C60- glycine) is developed. The sorption characteristics of the obtained nanocomposites are investigated. It is established that the greatest degree of filling the surface of silica is achieved when using fullerene C60-trismalonyl as a modifier. The surface morphology and the porous structure of the nanocomposite based on aminated aerosilogel and fullerene C60-trismalonyl are studied. It is found that during modification of the silica surface with fullerene C60- trismalonyl the nature of pore size distribution remains, and a slight change occurs in the most probable effective pore size and specific surface.
