COMPOSITE AND METHODS OF PRODUCTION

摘要

This invention relates to composite materials and methods of their production. More especially the invention provides methods of making a composite material by paste polymerisation comprising the steps of a) forming an emulsion of at least one polymerisable monomer in an aqueous material b ) polymerising the emulsion to provide a latex comprising particles of polymer, c) adding nanoparticles to the latex said nanoparticles having at least one dimension in the range 0.5 to 200nm, and d) spray-drying the latex.
