Abstract: a composite barrier film, comprising: an ultra-thin barrier film, wherein the ultra-thin barrier film is capable of being water-resistant and oxygen-resistant; and a protection film, being attached on the ultra-thin barrier film for increasing the stiffness of the ultra-thin barrier film, wherein a thickness of the ultra-thin barrier film is less than a thickness of the protection film.

Abstract: The invention is directed to a novel sealing composition and a method for improving performance of an electrophoretic display, especially at high temperatures. The invention is also directed to an electrophoretic display comprising display cells wherein said display cells are filled with an electrophoretic fluid and sealed with a sealing layer formed from a sealing composition comprising a thermoplastic elastomer and a crosslinking system.

Abstract: The invention relates to electrophoretic displays comprising core-shell pigment particles having a core of low specific gravity and low refractive index and a shell of high refractive index.

Abstract: The present invention is directed to a novel reactive protective colloid system suitable for stabilizing an electrophoretic display in which a halogenated solvent, particularly a fluorinated, more particularly a perfluorinated, solvent, or a mixture thereof, is used as the dielectric solvent.

Abstract: A Porous ceramic filter and its method of production are disclosed. The ceramic filter has at least one porous layer (or skin) made of a binder formed of a cured ceramic powder and a preceramic or pyrolyzed ceramic precursor optionally containing a source of zirconia. In some embodiments, the binder is formed of the zirconia source only. The presence of the zirconia gives a skin with good mechanical strength and corrosion resistance to both acidic and basic solutions.
