Abstract

We successfully achieved inclusion of fullerene (C60) into the grafted-poly(MMA-NMA) chains in THF without inducing the formation of C60 clusters and/or aggregation between the polymer-grafted silica particles. Polymer grafting onto silica was conducted by reacting 12nm colloidal silica particles with polymeric silane, prepared by radical polymerization, in THF without particle aggregation. Molecules of C60 were effectively included into grafted polymer chains in the THF suspension of the poly(MMA-NMA)-grafted silica, prepared from polymers with molecular weights of 33 200 and 48 000, without the formation of C60 clusters and without aggregation between the silica composite particles. It was observed that the maximum C60inclusion into poly(MMA-NMA) chains grafted on 11.2 mg silica particles was 0.25 mg, corresponding to 2.7 C60 molecules per unit SiO2 particle.
