Abstract
A two step method for preparing a filler composition, the filler composition useful to prepare a nanocomposite polymer and an epoxy nanocomposite coating. First, disperse a water dispersible filler material in a liquid comprising water, but without any added intercalation agent, to form a dispersion. Second, replace at least a portion of the water of the liquid with an organic solvent so that the water concentration of the liquid is less than six percent by weight to form the filler composition, the average size of at least one dimension of the filler material being less than two hundred nanometers upon examination by transmission electron microscopy of a representative freeze dried sample of the dispersion of the first step. A nanocomposite polymer can be prepared by mixing the filler composition with one or more polymer, polymer component, monomer or prepolymer to produce a polymer containing the filler composition.
