    Abstract: A method of forming transflective LCD panel includes forming a compensation material having reactive liquid crystal monomers, thermal initiators and a solvent on a first substrate. Then, a first heating process is performed on the compensation material to remove parts of the solvent and then a photo-polymerizing process is performed, and parts of the compensation material disposed in a reflective region are turned into birefringent zones. Moreover, a second heating process is performed, in which the first substrate is kept in a predetermined temperature for a predetermined time, and thereafter nitrogen gas flows in to the chamber to form a non-oxygen condition. Accordingly, parts of the compensation material disposed in a transmission region are turned into isotropic zones. The predetermined temperature of the second heating process is higher than the clearing point of the reactive liquid crystal monomers.

  • Patent number: 6358570
    Abstract: The present invention is the formation of solid polymer layers under vacuum. More specifically, the present invention is the use of “standard” polymer layer-making equipment that is generally used in an atmospheric environment in a vacuum, and degassing the liquid material prior to injection into the vacuum. Additional layers of polymer or non-polymer may be vacuum deposited onto solid polymer layers. Formation of polymer layers under a vacuum improves material and surface characteristics, and subsequent quality of bonding to additional layers. Further advantages include use of less to no photoinitiator for curing, faster curing, fewer impurities in the polymer electrolyte, as well as improvement in material properties including no trapped gas resulting in greater density, and reduced material wetting angle that facilitates spreading of the material and provides a smoother finished surface.

  • Patent number: 5631049
    Abstract: A formulation for a resilient gasket coating which is curable by ultraviolet radiation without emitting fumes into the surrounding environment. Different portions of the coating are cured by successive exposure to two different wavelengths of ultraviolet radiation during a continuous in-line process. The first wavelength cures an inner portion of the coating and bonds the coating to the substrate. The second wavelength cures a coating surface. The formulation permits ultraviolet curing of thicker pigmented coatings than have been previously known.

  • Patent number: 5580650
    Abstract: A process is disclosed for the formation of a high flux composite membrane having a thin discriminating film affixed to a porous support layer through a glue layer. The process comprises the formation of the discriminating film by irradiating an aqueous polymer solution in the substantial absence of drying and under conditions which are sufficient to form a polymer film on the surface of the polymer solution at the interphase of the solution and a blanketing fluid. The film is then affixed to the support through the glue layer which may be the same polymer solution from which the discriminating film is formed.

    Abstract: The present invention discloses an improved method of producing a low-cost, nitrogen-based inert atmosphere suitable for radiation curing of resins, coatings, etc. from non-cryogenically generated nitrogen. According to the disclosed method, residual oxygen present in non-cryogenically generated nitrogen is converted to either moisture or a mixture of moisture and carbon dioxide by reaction with a reducing gas in a catalytic reactor prior to using the nitrogen-based atmosphere for radiation curing of moisture insensitive materials such as resins and coatings.

  • Patent number: 5439736
    Abstract: Plasma polymerization of a fully alkylated disiloxane is greatly enhanced by the addition of oxygen to the plasma feed gases. Deposition rate of polysiloxane polymerizate upon substrates is increased, and the deposits are nontacky. Composite permselective membranes made by deposition of plasma-polymerized polysiloxanes in the presence of oxygen are useful for applications such as gas separations. Composite hollow fiber membranes of polysiloxane polymerizate on porous polypropylene exhibit oxygen/nitrogen permselectivities greater than 2.3 combined with increased oxygen permeability.
