Publication number: 20120136093Abstract: 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.Type: ApplicationFiled: January 16, 2012Publication date: May 31, 2012Applicants: THE TEXAS A & M UNIVERSITY, DOW GLOBAL TECHNOLOGIES LLCInventors: Luyi Sun, Woong Jae Boo, Hung-Jue Sue, Maurice J.

Patent number: 7482382Abstract: 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.Type: GrantFiled: May 19, 2004Date of Patent: January 27, 2009Assignees: The Texas A&M University System, Kaneka CorporationInventors: Yuntao Li, Hung-Jue Sue, Riichi Nishimura, Nobuo Miyatake
