  • Patent number: 11976386
    Abstract: A method of preparing a carbon fiber including: preparing a precursor fiber for preparing a carbon fiber; and stabilizing the precursor fiber. The stabilization of the precursor fiber includes a first stabilization phase, a second stabilization phase, a third stabilization phase, and a fourth stabilization phase, which are set at four different temperatures between a temperature at which heat starts to be generated from the stabilization reaction of the precursor fiber and a temperature at which the generation of heat is maximized. Ozone gas is input while at least one phase of the third stabilization phase and the fourth stabilization phase is carried out.

  • Patent number: 10955589
    Abstract: An optical coating, such as anti-reflective coating (ARC) or colored coating for optical devices, suitable especially for mobile devices. The ARC is made up of alternating layers of low refractive index and high refractive index. At least one of the layers, preferably the top layer, is made up of nano-laminate. The nano-laminate is a structure of alternating nano-layers, each nano-layer made out of a material having refractive index similar to the layer it replaces. Optionally, each of the layers are made up of nano-laminates, such that a layer having low refractive index is made up of nano-laminates of nano-layers having low refractive index, while high index layers are made up of nano-lamonate of nano-layers having high refractive index. Each of the nano-layers is of 2-10 nanometer thickness.

  • Publication number: 20200354826
    Abstract: A method for forming a diamond-like carbon (DLC) coating on an article is provided, comprising: alternatingly performing a deposition process and an ashing process on the article a determined number of times, wherein during the deposition process the method proceeds by forming on the article a layer of DLC which includes graphitic sp2 carbon and tetrahedral sp3 carbon, and during the ashing process the method proceeds by selectively etching the graphitic sp2 carbon, wherein the determine number of time is configured to result in a designated overall thickness of the DLC coating.
