  • Publication number: 20140021400
    Abstract: The present invention relates to a novel printable paste composition and its use in etching conductive films formed by a plurality of interconnecting silver nano-wires. After etching, the conductive film has a pattern of conductive and non-conductive areas with low visibility. The etched films are suitable as a transparent electrode in visual display devices such as touch screens, liquid crystal displays, plasma display panels and the like.

  • Publication number: 20080113117
    Abstract: Disclosed herein are light diffusing films, methods of making the same and articles using the same. In one embodiment, a method of making a light-diffusing film comprises: mixing about 90 wt. % to about 99.999 wt. % of a powdered polycarbonate and about 0.001 wt. % to about 3 wt. % light-diffusing particles to form a mixture, wherein weight percents are based on a total weight of the light-diffusing film; melting the mixture to form a melt; and extruding the melt in the form of a sheet to form the light-diffusing film. The light-diffusing film comprises a hiding power of about 0 to 0.

  • Patent number: 7297381
    Abstract: Disclosed herein are light diffusing films, methods of making the same and articles using the same. In one embodiment, a light diffusing film is formed from a composition comprising: a polycarbonate, phosphite stabilizer, epoxy stabilizer, hindered phenol stabilizer, and light diffusing particles having a refractive index of about 1.3 to about 1.7. The film comprises a hiding power of 0 to about 0.5. In one embodiment, a method for producing a film comprises combining a polycarbonate, a phosphite stabilizer, an epoxy stabilizer, and light diffusing particles to form a combination, and forming the combination into the film.
