Patent number: 10294416Abstract: Yellow electrochromic polymers (ECPs) are prepared that display a yellow neutral state and a highly transmissive oxidized state. The ECPs are copolymers where a dyad of dioxyhetereocyclic repeating unis alternate with a monad of an aromatic repeating unit. An alternate yellow ECP has an oxidation potential of 450 mV or less and is an alternating copolymer of an acyclic dioxythiophene (AcDOT) or a propylene dioxythiophene (ProDOT) with an aromatic repeating unit that has an electron donating substituent. The yellow ECPs can be processed from solution for electrochromic devices.Type: GrantFiled: May 28, 2015Date of Patent: May 21, 2019Assignee: GEORGIA TECH RESEARCH CORPORATIONInventors: Justin Adam Kerszulis, John Robert Reynolds, Aubrey Lynn Dyer

Patent number: 10294326Abstract: Copolymers including dioxythiophene repeating units and no acceptor units allow the formation of electrochromic polymers (ECPs) with vivid neutral state colors and very colorless oxidized states that can be switched rapidly. The dioxythiophene repeating units can included in sequences where all of one type of dioxythiophene is included exclusively as isolated dyads or triads within the copolymer, or the copolymer can be an alternating copolymer with propylenedioxythiophene units. Other non-acceptor units can be included in the copolymers. The copolymers are rendered organic solvent soluble by alkyl substituents on repeating units. The inclusion of sterically encumbered acyclic dioxythiophene (AcDOT) units promotes red color while unsubstituted ethylenedioxythiophene (EDOT) units promote blue colors, and their respective content can be manipulated to achieve a desired neutral state color. Soluble copolymers comprising at least 50% EDOT repeating units can be used in supercapacitor applications.Type: GrantFiled: May 22, 2015Date of Patent: May 21, 2019Assignee: UNIVERSITY OF FLORIDA RESEARCH FOUNDATION, INCORPORATEDInventors: John Robert Reynolds, Michael R.

Patent number: 9411209Abstract: An electrochromic cell includes a minimally color changing polymer (MCCP) and a non-color changing polymer (NCCP), where the neutral state or the oxidized state is highly transmissive in the NIR and the oxidized state or the neutral state, respectively, is significantly less transmissive in the NIR. An electrochromic device (ECD) can include the electrochromic cell, or a combination of electrochromic cells. The ECD can be part of a window or a laminate for a window to permit the control of IR transmittance through the window.Type: GrantFiled: June 28, 2012Date of Patent: August 9, 2016Assignee: UNIVERSITY OF FLORIDA RESEARCH FOUNDATION, INC.Inventors: John R.

Publication number: 20140175281Abstract: An electrochromic device (ECD) includes an electrochromic cell and, optionally, one or more additional electrochromic cells where all cells are parallel, and where at least one of the electrodes of one of the cells comprises a single-walled carbon nanotube (SWNT) film The electrochromic cells allow the control of transmittance of two or more different portions of the electro-magnetic spectrum through the ECD. One cell can control the transmittance of visible radiation while the other cell can control the transmittance of IR radiation. The ECD can be employed as a “smart window” to control the heat and light transmission through the window. The ECD can be in the form of a laminate that can be added to an existing window.Type: ApplicationFiled: June 28, 2012Publication date: June 26, 2014Applicant: University of Florida Research Foundation, Inc.Inventors: John R.

Patent number: 8519090Abstract: Embodiments of the invention are directed to yellow-to-transmissive conjugated polymers, a method to prepare the yellow conjugated polymers, the use of the yellow conjugated polymers in an electrochromic and/or electroluminescent device comprising neutral state primary subtractive colored conjugated polymers, and a method to prepare the device comprising the yellow conjugated polymer. The yellow conjugated polymers comprise a sequence of dioxythiophene units alternating with aromatic units, thiophene units, furan units, and/or pyrrole units. The yellow conjugated polymers are prepared by cross-condensation reactions. The yellow conjugated polymers can be soluble and preparation of the device involves deposition of the yellow conjugated polymer from solution onto a surface.Type: GrantFiled: February 25, 2013Date of Patent: August 27, 2013Assignee: University of Florida Research Foundation, Inc.Inventors: Chad Martin Amb, Justin Adam Kerszulis, John R.

Patent number: 8284473Abstract: A dual active electrochromic device is a combination of at least two working electrodes that contain electrochromic materials and at least one counter electrode where the potentials between each working electrode and a counter electrode are independently supplied. No more than one electrode is reflective. The color of the device results from the additive color of the electrochromic materials and varies according to the potentials applied independently. The electrochromic materials can be electrochromic polymers that are deposited as film on substrates to form the working electrodes. The electrochromic device can be used for display or window applications.Type: GrantFiled: March 24, 2009Date of Patent: October 9, 2012Assignee: University of Florida Research Foundation, Inc.Inventors: John R.
