摘要

Organic-inorganic nanocomposite particles comprising polymer chains and silica are of considerable academic and industrial interest. For example, BASF currently manufacture film-forming copolymer/silica nanocomposite particles that are marketed by AkzoNobel under the ‘Symbiotec’ trade name. Such fa?ade coatings exhibit superior dirt-shedding properties, better uv resistance and enhanced blocking resistance. Several review articles on the academic advances in this sub-field have recently been published. The combination of a glycerol-modified silica sol and a cationic azo initiator has already been reported to produce poly(styrene-co-n- butyl acrylate)/silica particles in aqueous media. Such nanocomposite particles have a well-defined core-shell morphology with relatively narrow particle size distributions. Furthermore, this robust formulation leads to very high silica aggregation efficiencies without requiring auxiliary (co)monomers, surfactants or non-aqueous (co)solvents.
