    DIFFUSION BARRIER COATINGS ON GLASS BY SOLUTION DERIVED NANOCOMPOSITE (SDN®) TECHNOLOGY

    By: Olivia Niitsoo, Christopher Mah, Rebecca Stamm, Jeff Dawley, Val Ryabov and Elmira Ryabova

    ABSTRACT:

    Glass is an integral component for modern technology – from consumer electronics like cell phone screens and OLEDs to large area photovoltaic (PV) panels, glass often serves as the substrate or superstrate in contact with transparent conducting oxides or other active layers. Thus, device performance depends on the chemical composition of the glass: alkali metal ion diffusion can deteriorate device performance over time. Use of a thin coating that blocks ion diffusion relaxes the demands to glass manufacturing and allows to source glass from different suppliers without compromising reproducibility.

    Diffusion barrier coatings are generally less than few hundred nanometers thick, dense coatings that have to withstand the subsequent processing steps (e.g. high temperature). Solution Derived Nanocomposite (SDN®) technology can produce barrier coatings that meet these demands without the complexities and cost associated with commonly used vacuum (PVD, ALD etc.) and chemical vapor deposition (CVD) techniques. SDN® barrier coatings are applied on glass sheets in a specially designed and patented Roll Coater without the need for vacuum technology at any stage of the process. Tuning of coating properties (thickness, refractive index etc.) is achieved by controlling physicochemical properties of the coating solutions. Optical properties and mechanical durability of SDN® barrier coatings will be discussed.

    SDN® diffusion barrier coating is a single-layer coating that blocks sodium ion diffusion, but also enhances optical properties by reducing reflectivity and improves abrasion resistance of glass.

    SOLUTION DERIVED NANOCOMPOSITE (SDN®) TECHNOLOGY FOR SCALABLE APPLICATION OF SPECTRALLY SELECTIVE OPTICAL COATINGS.

    Niitsoo, V. Ryabov, J. Dawley, P. Wang, E. Ryabova  | Glass Performance Days 2013, June 13, 2013, Tampere, Finland

    ABSTRACT:

    Low-emission (low-e) coatings on architectural glass are a key component for creating sustainable, energy-efficient buildings. They act as optical filters that selectively reflect incoming infrared radiation while transmitting visible wavelengths. We present Solution Derived Nanocomposite (SDN®) technology – a unique alternative to the commonly used vacuum (PVD, CVD, ALD etc.) and non-vacuum (electroplating, CBD, screen-printing etc.) deposition techniques. The key advantages of SDN® are excellent uniformity and purity of the deposited films, substantially lower capital and operating costs, high throughput and material utilization, and low waste treatment cost. SDN® coatings are applied on glass sheets in a specially designed and patented Roll Coater without the need for vacuum technology at any stage of the process. Tuning of optical and other properties is achieved by controlling physicochemical properties of the coating solutions. Unlike metal-based low-e coatings, SDN® low-e coating does not interfere with transmission of cellular communication frequencies. Environmental testing shows excellent durability of SDN® low-e coatings on glass. In addition to low-e coatings, SDN® technology with the Roll Coater allows the production of transparent conductors, electro-chromic films, abrasion- and scratch- resistant coatings, and antifogging coatings.
