  • HIGH TRANSPARENCY, HIGH HAZE NANOSTRUCTURED STRUCTURES
    Publication number: 20230365457
    Abstract: The invention relates generally to optically high transparency and high haze structures and, more particularly, to plastic, e.g., polymer, and glass structures having a sub-wavelength texture formed on a surface thereof, which is effective to impart the optical properties of high transparency and high haze to the structures. The texture is in a grass-like or needle-like form. Additionally, the optically high transparency and high haze structures may include a transparent conductor. Furthermore, the glass structures may exhibit a self-cleaning function.
    Type: Application
    Filed: July 25, 2023
    Publication date: November 16, 2023
    Applicant: UNIVERSITY OF PITTSBURGH - OF THE COMMONWEALTH SYSTEM OF HIGHER EDUCATION
    Inventors: SAJAD HAGHANIFAR, BRADLEY D. PAFCHEK, PAUL W. LEU, TONGCHUAN GAO

  • Superomniphobic, flexible and rigid substrates with high transparency and adjustable haze for optoelectronic application
    Patent number: 11747700
    Abstract: The invention relates generally to optically high transparency and adjustable haze, superomniphobic, rigid and flexible structures and, more particularly, to fused silica glass and flexible plastic, e.g., polymer, structures having a sub-wavelength texture formed on a surface thereof, which is effective to impart the optical properties of high transparency and adjustable haze to the structures. The texture is reentrant. Additionally, the optically high transparency and adjustable haze structures include a silicon dioxide coating applied to the texture and a treatment of a low surface energy material deposited on the silicon dioxide coating. The silicon dioxide coating renders the structures super hydrophilic, and the low surface energy material treatment renders the structures superomniphobic.
