Definitions

  • the invention relates to a multi-layered glass structure for the changing of its light permeability which contains a closed space between two or more transparent pieces of glass or plastic
  • the subject of the invention is the multi-layered glass so called intelligent glass
  • intelligent glass This is a sandwich structure which, between two glass sheets or transparent plastic layers, contains a thin polymer system Its external appearance form is deceptively similar to sheet glass that is in commercial dist ⁇ bution, in other words the polymer system does not degrade the optical characte ⁇ stics
  • the adapting ability of the intelligent glass is provided by the polymer layer Its optical characte ⁇ stics - for example transparency - are greatly influenced by environmental effects like for example temperature change or the presence of an electric field The change in the environment may bring about changes in the intelligent glass that cause the o ⁇ ginally transparent glass to become opal glass, cloudy, only allowing light through to a much smaller degree This transparent glass - opal glass transition can take place in both directions
  • the glass - opal glass transition can be brought about by our by switching on an elect ⁇ c circuit
  • the transparency or opacity of internal windows can be controlled with the switching on or off of a switch
  • Intelligent glass is suitable for making a new type of display It is possible to w ⁇ te letters of the required size in the polymer, or a drawing These may be called up and made to disappear with a thermal of elect ⁇ cal effect
  • Intelligent glass changes its optical characte ⁇ stics due to a thermal or elect ⁇ cal effect suddenly - not gradually - in a way that may be reversed
  • the layer between the layers of glass is responsible for this change
  • This layer may be of a cross-linked or non-cross-linked homopolymer, co-polymer, polymer solution, polymer gel or a mixture containing polymer, solvent (solvents) and other small molecule components which have lower or upper (or both) plait point temperatures, or other transformation temperatures that affect optical characte ⁇ stics (like, for example, the Kraft point or the clouding point)
  • How the intelligent glass changes its optical characteristics depends on the layer's phase characteristics. In the case of a lower plait point an increase in the temperature brings about the glass - opal glass transition. The opposite of this takes place in the case of an upper plait point.
  • the value of the temperature of electric parameters bringing about the glass - opal glass transition may be changed between a wide range by changing the chemical structure of the layer and the additive materials put in the layer.
  • phototropic glass When visible light is radiated on this its light transmission ability gradually decreases, which process is reversible. In phototropic glass the linking of two significantly different phenomena results in the non-sudden change of the optical characteristics.
  • the multi-layered glass structure that forms the subject of our invention is different from the above-mentioned types of glass both from the points of view of its chemical structure and operating method. At the same time its much cheaper material and production cost and the sudden changing of its optical characteristics creates the conditions for its wider area of application. To the best of our knowledge the application of gels to produce glass with regulatable light permeability is not known in the specialist literature.

Abstract

L'invention concerne une structure de verre multicouche dont la perméabilité à la lumière peut changer. Ladite structure comporte un espace clos entre deux pièces transparentes de verre ou de plastique au moins. La structure selon l'invention est caractérisée en ce que l'espace clos contient un mélange constitué de 0,1-100 % de polymère, de 0-99 % d'un solvant ou un mélange de solvants dans une structure de gel et de 0-50 % d'un matériau dissous.
