Abstract: A light control film is described comprising alternating transmissive regions and absorptive regions disposed between the light input surface and the light output surface. The absorptive regions have an aspect ratio of at least 30. In some embodiments, an absorptive layer or reflective layer is disposed between the alternating transmissive regions and absorptive regions and the light input surface and/or light output surface. In another embodiment, the alternating transmissive regions comprise an absorptive material. The light control film can exhibit low transmission of visible light and high transmission of near infrared light. Also described is a light detection system comprising such light control films and a microstructured film.

Abstract: Methods of making metal patterns on flexible substrates are provided. Releasable solid layer is selectively formed on a patterned surface of the flexible substrate by applying a liquid solution thereon. Metal patterns on the flexible substrate can be formed by removing the releasable solid layer after metallization. In some cases, the releasable solid layer can be transferred from the patterned surface to a transfer layer where the metal patterns are formed.

Abstract: A system and methods for sterilizing or disinfecting articles, particularly the hollow internal areas of medical instruments are disclosed. The system includes a plasma generator having an electrode, a shield, and a dielectric gap between the electrode and the shield. A source of electrical power is connected to the plasma generator for applying an electron energy density between the electrode and the shield. A source of gas comprising water vapor, oxygen and nitrogen provides a flow of gas between the electrode and the shield, to form a plasma containing acidic and/or oxidizing species. In the exemplary system, the temperature at the shield's surface is 0.05 eV/molecule of the gas. Also disclosed is a method for disinfecting an article contaminated with a bio-film or spores, by exposing the contaminated article to the plasma for an exposure time sufficient to achieve at least 2-log10 reduction in colony forming units.

Abstract: A light control film is described comprising a light input surface and alight output surface opposite the light input surface; alternating transmissive regions and absorptive regions disposed between the light input surface and the light output surface, wherein the absorptive regions comprise light-absorbing or light-reflecting particles and a dried aqueous dispersion of an organic polymer. The light control film can have improved on-axis transmission in combination with sufficiently high sheet resistance such that the film does not detract from the responsiveness of a touch screen of an electronic device. Also described is a coated article and method of making.
