  • Patent number: 10698139
    Abstract: A diffuse reflecting optical construction that does not rely on special molds or tooling of the prior art in order to create a critical diffuse reflecting surface feature of the optical construction. An atomized spray method is employed to apply a hardenable transparent liquid polymer layer to the surface of a prefabricated base optical substrate. The polymer layer forms beads on the surface of the prefabricated base optical substrate, resulting in the formation of a surface having a random and continuous series of peaks and valleys thereon that form the diffuse reflecting surface feature. The prefabricated base optical substrate having the diffuse reflecting polymer layer thereon combined with additional optical layers forms a transparent diffuse reflecting optical construction that can be used in the manufacture of optical lenses, windows, and transparent films that reflect light in a diffuse manner while transmitting light in a substantially undistorted manner.

  • Publication number: 20150132479
    Abstract: The invention relates to a method of making hybrid organic-inorganic core-shell nano-particles, comprising the steps of a) providing colloidal organic particles comprising a synthetic polyampholyte as a template; b) adding at least one inorganic oxide precursor; and c) forming a shell layer from the precursor on the template to result in core-shell nano-particles. With this method it is possible to make colloidal organic template particles having an average particle size in the range of 10 to 300 nm; which size can be controlled by the comonomer composition of the polyampholyte, and/or by selecting dispersion conditions. The invention also relates to organic-inorganic or hollow-inorganic core-shell nano-particles obtained with this method, to compositions comprising such nano-particles, to different uses of said nano-particles and compositions, and to products comprising or made from said nano-particles and compositions, including anti-reflective coatings and composite materials.

  • Patent number: 9023440
    Abstract: The invention provides a liquid crystal alignment film, a method for preparing the same and a liquid crystal display device comprising the same. The alignment film comprises a polyimide obtained by reacting a compound as shown in Formula 2 or Formula 3 with an aromatic diamine as shown in Formula 1, wherein the R1, R2, R3, R4, R5, R6, R7, R1?, R2?, R3?, R4?, R5?, R6?, R7?, or R8? is H, an alkyl, an aralkyl or a haloalkyl, and the Ar is an aryl. The liquid crystal alignment film has a tactic spatial configuration, decreases the ?-? attractive interaction between the polyimide backbones, allows the directional and homogenous alignment of the liquid crystal molecules on the surface of the polyimide, and thereby increases the contrast of the liquid crystal display.
