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.

摘要： The present invention is directed to novel sol-gel methods in which metal oxide precursor and an alcohol-based solution are mixed to form a reaction mixture that is then allowed to react to produce nanosized metal oxide particles. The methods of the present invention are more suitable for preparing nanosized metal oxide than are previously-described sol-gel methods. The present invention can provide for nanosized metal oxide particles more efficiently than the previously-described sol-gel methods by permitting higher concentrations of metal oxide precursor to be employed in the reaction mixture. The foregoing is provided by careful control of the pH conditions during synthesis and by ensuring that the pH is maintained at a value of about 7 or higher.
