  • Patent number: 8460591
    Abstract: The instant disclosure relates to porous membranes and methods of making the same. An example of the method includes exposing a polymeric film (including a polymer and i) a gel-forming polymer, ii) ceramic particles, or iii) combinations of i and ii) established on a carrier belt to a non-solvent or a slightly miscible solvent of a polymer in the polymeric film, thereby inducing formation of a porous structure in the polymeric film. The method further includes transporting the polymeric film on the carrier belt into a bath of a non-solvent or a slightly miscible solvent of the polymer for a predetermined time thereby finalizing the formation of the porous structure and forming the porous membrane. The porous membrane is removed from the non-solvent or slightly miscible solvent bath.

  • Patent number: 8372318
    Abstract: A plurality of substantially conical or pyramidal elements are formed inside a sheet-like binder. The binder has smooth surfaces. The elements and the binder cooperate to refract light incident on a brightness enhancement sheet from a surface on a diffusion sheet side to the other surface in a direction normal to the brightness enhancement sheet. Thus, the front brightness is enhanced. The elements are distributed along one of the surfaces of the brightness enhancement sheet with vertices pointing in one direction toward one of the surfaces. The elements are formed by trapping gas bubbles in the binder and differ in refractive index from the binder.
