Abstract:
Provided is a coloring pattern structure. The coloring pattern structure includes: a substrate; a light-transmitting dielectric layer formed on at least one surface of the substrate; and a composite material layer disposed on an upper surface of the light-transmitting dielectric layer and formed of a metal and a first material not having a thermodynamic solid solubility in the metal, wherein the metal included in the composite material layer has a pattern coated only on portions of the upper surface of the light-transmitting dielectric layer, and the first material is coated on the remaining area where the metal is not coated.
Abstract:
Provided is a technique for electroless deposition (ELD) for forming metal conductive layer on an insulating substrate made of glass, polymer, etc. According to an aspect, an adhesive layer and a catalyst layer are formed on a substrate using a dry deposition method, such as are plasma deposition (APD) or sputtering, etc., and electroless deposition is performed thereon, thereby forming a metal thin, film. Therefore, it is possible to significantly simplify a complicated pretreatment process required for electroless depositions and increase adhesive strength of a deposited metal thin film.
Abstract:
Provided are a method of manufacturing a honeycomb metal structure by using aluminum (Al) powder and a metal catalyst module including the honeycomb metal structure. The method includes preparing a honeycomb structure including at least one substrate including iron (Fe), coating at least a part of the substrate with a viscid material whose viscosity is increased by moisture, attaching metal powder onto the viscid material, adhering the metal powder to the substrate by supplying the moisture to the viscid material, and generating an uneven structure made of the metal powder bonded to the substrate, by performing heat treatment of the substrate onto which the metal powder is adhered.
