ABSTRACT:
A structure consisting of two cover layers sandwiching a polymer and solvent layer is useful for making automatic light valves. Mechanical and optical properties are improved by a novel continuous network of bonds which transmit stresses from one cover layer, to and among the polymer chains, and then to the second cover layer. The laboratory and factory preparation methods necessitated by this layered and bonded structure are described. These automatic light valves may be used for making optical displays, processing information, and building apertures.
