Patent number: 4837592Abstract: This invention teaches an electrochromic device in which an electrochromic layer is positioned between two electrodes. The electrochromic layer comprises an inorganic based bulk material supporting electrochromic particles and ion producing particles in fixed but generally distributed positions therewithin. The bulk material permits migration of ions produced by the ion producing particles to and from the electrochromic particles upon change in voltage between the first and second electrodes. The bulk material also prohibits the passage of electrons therethrough when a voltage is applied between the first electrode and the second electrode, whereby an electric field is built up between the first and second electrodes which causes migration of the ions. A preferred method of making a material which can form an electrochromic layer is also disclosed.Type: GrantFiled: December 24, 1987Date of Patent: June 6, 1989Assignee: Ford Motor CompanyInventor: Hulya Demiryont

Patent number: 4830471Abstract: This invention teaches uncolored copper oxide as a new electrochromic material. An electrochromic device is constructed from this material by forming either an anodic electrochromic device or a cathodic electrochromic device. A fast ion conductor is also provided which is capable of generating ions when an electric field is applied thereto. The fast ion conductor also permits ion movement therethrough while prohibiting electron movement therethrough. The fast ion conductor and the uncolored copper oxide are arranged between an anode and a cathode to form an electrochromic device. Preferably, the copper oxide is in a layer next to one of the electrodes. If the copper oxide layer is next to the cathode, the device is a cathodic device which can generate a blue color. If the copper oxide layer is next to the anode, the device is an anodic device and can be operated to produce either a pink or a green color depending upon the amount of voltage applied between the anode and the cathode.Type: GrantFiled: December 24, 1987Date of Patent: May 16, 1989Assignee: Ford Motor CompanyInventor: Hulya Demiryont

Patent number: 4810067Abstract: This invention teaches an electrochromic device in which an electrochromic layer is positioned between two electrodes. The electrochromic layer comprises an organic based bulk material which has been polymerized and condensed supporting electrochromic particles and ion producing particles in fixed but generally distributed positions therewithin. The bulk material permits migration of ions produced by the ion producing particles to and from the electrochromic particles upon change in voltage between the first and second electrodes. The bulk material also prohibits the passage of electrons therethrough when a voltage is applied between the first electrode and the second electrode, whereby an electric field is built up between the first and second electrodes which causes migration of the ions. Also my invention is a method of making a material which can form an electrochromic layer. The method has the following steps. A gel producing organic material is dissolved in a solvent to produce a solution.Type: GrantFiled: December 24, 1987Date of Patent: March 7, 1989Assignee: Ford Motor CompanyInventor: Hulya Demiryont
