Patent number: 8446666Abstract: The present invention discloses a non-quarter wave multilayer structure having a plurality of alternating low index of refraction material stacks and high index of refraction material stacks. The plurality of alternating stacks can reflect electromagnetic radiation in the ultraviolet region and a narrow band of electromagnetic radiation in the visible region. The non-quarter wave multilayer structure, i.e. nLdL?nHdH??0/4, can be expressed as [A 0.5 qH pL(qH pL)N 0.5 qH G], where q and p are multipliers to the quarter-wave thicknesses of high and low refractive index material, respectively, H is the quarter-wave thickness of the high refracting index material; L is the quarter-wave thickness of the low refracting index material; N represents the total number of layers between bounding half layers of high index of refraction material (0.5 qH); G represents a substrate and A represents air.Type: GrantFiled: May 18, 2009Date of Patent: May 21, 2013Assignees: Toyota Motor Engineering & Manufacturing North America, Inc., Toyota Motor Corporation, Massachusetts Institute of TechnologyInventors: Pinar Kurt, Debasish Banerjee, Robert E. Cohen, Michael Rubner, Masahiko Ishii, Minjuan Zhang

Patent number: 7842388Abstract: Polymers, and particularly conventional commodity bulk polymers, are modified to have a surface activity of interest using a surface modifying polymer that includes a moiety that favors migration to the surface of the bulk polymer together with a moiety provides the activity of interest (e.g., biocidal, wettability modifying (hydrophobic or hydrophilic), resistance to radiant energy, providing a functional group for functionalizing the surface, etc.). The surface modifying polymer is combined with the bulk polymer, and, due to the presence of the moiety that favors migration, concentrates primarily on the surface of the bulk polymer such that the moiety that provides the activity of interest is located primarily on the surface of the bulk polymeric article which is produced. Advantageously, only a minimal amount (such as, e.g., about 2 weight %) of polymeric surface modifier is needed. Being able to achieve desired properties (such as biocidal activity, wettability modification, etc.Type: GrantFiled: March 14, 2006Date of Patent: November 30, 2010Assignee: Virginia Commonwealth UniversityInventors: Kenneth Joseph Wynne, Biao Duan, Steven Grunzinger, Umit Makal, Pinar Kurt
