Adjustable tint window with electrochromic conductive polymer
First Claim
1. A method for decreasing radiative heat transfer and adjustably limiting visible light and near infrared radiation transfer ad glare through a window, comprising the steps of:
- (a) mounting within a frame of said window a plurality of spaced window panes, a first and second of said panes having opposing faces;
(b) assembling between said opposing faces a conductive polymer cell, said cell having a first wall composed of a transparent conductive layer affixed to said first pane and having deposited thereupon an electroactive electro-optically responsive conductive polymer composed of either p-type or n-type conjugated polymers and a second wall comprised of a transparent conductive layer coated on said second pane, said layer being optionally coated with a second electro-optically responsive conductive polymer, said conjugated polymers being chain-oriented in a plane parallel to the plane of the window so as to create a polarization of the transmitted light, said first and second walls delimiting a cavity containing an ion-conducting electrolyte which contacts opposing surfaces of the first and second walls, and (c) applying a potential between said first and second walls to provide a selected light transmittance upon passage of current therebetween.

Abstract
A method is provided for decreasing radiative heat transfer and adjustably limiting visible light and near infrared radiation transfer and glare through a window. The method comprises the steps of: (a) mounting within a frame of the window a plurality of spaced window panes, a first and second of the panes having opposing faces; (b) assembling between the opposing faces a conductive polymer cell, the cell having a first wall composed of a transparent conductive layer affixed to the first pane and having deposited thereupon an electroactive electro-optically responsive conductive polymer, and a second wall comprised of a transparent conductive layer coated on the second pane, the layer being optionally coated with a second electro-optically responsive polymer, the first and second walls delimiting a cavity containing an ion-conducting electrolyte which contacts opposing surfaces of the first and second walls, and (c) applying a potential between the first and second walls to provide a selected light transmittance upon passage of current therebetween.
