Abstract

Dispersion of C60/silica nano-composite, prepared by inclusion of C60 into grafted polymer chains on silica, in organic solvent and poly(methyl methacrylate) (PMMA) matrix was investigated. The polymer-grafted SiO2 particles were prepared by grafting of poly(methyl methacrylate-co-2-naphthyl methacrylate) onto colloidal silica of 9.1 nm in diameter. Inclusion of C60 into the grafted polymer chains was significantly dependent on molecular weight of the polymer and independent on amounts of grafted polymer. The C60/SiO2-PMMA hybrid film, composed of 0.21% C60 and 10% SiO2, showed high transparency in visible light region.
