  • Patent number: 12287456
    Abstract: A hard optical film, a method for producing the same and use thereof. The film is an optical film with a nano-dual-phase structure, and features a regulable thickness, high visible light transmittance and hardness, a flat and uniform surface, and a great application prospect. The hard optical film is prepared on a surface of a substrate by magnetron sputtering, having high binding force between the obtained film and the substrate, such that the substrate has a very high hardness, a very strong abrasion resistance and certain corrosion resistance.

  • Publication number: 20250118454
    Abstract: A metal grid flexible transparent conductive film and its preparation method and applications are provided. The conductive film has a flexible substrate and a sputtered metal grid, the metal grid forming various desired patterns on the flexible substrate. Magnetron sputtering method is used to accurately control the thickness of the metal grid layer by controlling the deposition time, so as to prepare a flexible transparent conductive film with good quality, high transmittance, high conductivity and strong bending resistance. The conductive film can be used as a flexible transparent electrode material with excellent properties, and can satisfy the demand of flexible display screen or flexible electronics, and the preparation process is simple, safe and non-toxic, and it can be convenient to prepare a large-area metal grid.

  • Patent number: 12234541
    Abstract: Disclosed are a polymer composite material and a preparation method thereof. The polymer composite material includes a polymer base layer and a metal thin film layer provided on a surface of the polymer base layer. The metal thin film layer is made of amorphous alloy. The surface of the polymer base layer is provided with a metal thin film with an amorphous structure. In this way, the arrangement of the metal thin film with amorphous structure can not only improve the mechanical properties, wear resistance and corrosion resistance of the polymer substrate material, but also can greatly improve the toughness of the polymer substrate material, to simultaneously improve the strength and toughness of the polymer material.
