    摘要： A method for preparing a filler composition useful for preparing a nanocomposite polymer is provided. The method includes a first step of dispersing a water dispersible filler material in a liquid comprising water to form a dispersion and a second step of replacing at least a portion of the water of the liquid with an organic solvent. The resulting filler composition features a water concentration of the liquid of less than six percent by weight, and the average size of at least one dimension of the filler material is 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, particularly and epoxy resin composition, can be prepared by mixing the above-made filler composition with one or more polymer, polymer component, monomer or prepolymer.

    摘要： A composition and method of making a stabilizer for polymers. The composition has zinc oxide (ZnO) nanoparticles dispersed and having an average size of no more than about 15 nanometers, wherein the ZnO nanoparticles are provided as an additive to a polymeric material, thereby forming a stabilized polymer composite in which the ZnO nanoparticles remain dispersed and have an average size of no more than about 15 nanometers. The stabilized polymer composite is stabilized against heat and ultraviolet light. The polymeric material can be a (meth)acrylic resin, a styrenic resin, a pre-cure epoxy resin, or combinations thereof. In a concentrated form, the composition has ZnO nanoparticles that are typically less than 20% of the stabilized polymer composite. The stabilizer is polymerizable and may include additional additives.
