Abstract

Compositions comprising surface-modified calcite nanoparticles dispersed in a curable resin and to coatings and fibrous composites incorporating such compositions are described. The nanocalcite particles have a high magnesium to calcium surface concentration ratio. The surface-modifying agents include a binding group ionically associated with the nanoparticles, and a compatiblizing segment compatible with the curable resin. The surface-modifying agent may also include a reactive group capable of reacting with the curable resin. Methods of preparing nanocalcite composites, and coatings and fibrous composites prepared from such nanocalcite composites are also described.
