Patent number: 7790841Abstract: Method for enhancing the crystallization rates of engineering thermoplastics through the use and incorporation of particulate additives with dimensions on the order of 10-1000 nm is described. The presence of nanoparticles at concentrations of, e.g., less than 10 weight percent of the composition, reduces the viscosity of the thermoplastics as compared to the respective homopolymer, thereby increasing polymer chain transport and diffusion to the crystallizing growth front. The prescription of this technology has been shown to reduce crystallization half times of some engineering thermoplastics by as much as 40 percent at optimal crystallization temperatures, an effect that is magnified as the temperature is reduced towards the glassy state of the amorphous phase. Nano-modified engineering thermoplastics with rapid crystallization kinetics and relatively low viscosities can be utilized in component fabrication processes that require rapid processing times, e.g., for the sake of cost efficiency.Type: GrantFiled: February 6, 2008Date of Patent: September 7, 2010Assignee: United States of America as represented by the Secretary of the Air ForceInventors: Gregory R.

These include improved tolerance for oily materials and improved skin feel. These polymers find use in personal care applications like pigmented products. In the personal care arena, solid products that do not experience syneresis are important. Syneresis is a condition that exists in a solid product that causes a liquid that is incompatible to ooze out, which is cosmetically unacceptable.Type: ApplicationFiled: July 29, 2008Publication date: February 4, 2010Inventors: Kevin Anthony O'Lenick, Anthony J. O'Lenick, JR.

Publication number: 20090257113Abstract: A light filter or an array of filters can be either one or two dimensional. The filter or filters use multiple beam interference by varying an optical path length between semi-reflective surfaces. The optical path length between the semi-reflective surfaces is varied by changing a thickness of a polymer film in response to an electric field formed between two semi-transparent electrodes. The filter can be configured in either a transmissive or reflective mode.Type: ApplicationFiled: May 30, 2007Publication date: October 15, 2009Inventor: Timothy Smith
