Thermoscattering Materials And Devices

US Patent:
6362303, Mar 26, 2002
Filed:
May 19, 2000
Appl. No.:
09/574625
Inventors:
Harlan J. Byker - Holland MI
Frederick A. Millett - Perrysburg OH
Paul H. Ogburn - Hudsonville MI
Assignee:
Pleotint, L.L.C. - West Olive MI
International Classification:
C08G 1848
US Classification:
528 76, 528 83, 116216, 116217, 428 67, 428913, 525176, 525440, 525454, 525458, 525460, 525931, 525932
Abstract:
Thermally reversible light scattering materials are provided in accordance with the invention including a low melting, polymeric material dispersed in a polymer matrix; a first polymer which upon heating from a temperature below its melting point to a temperature above its melting point changes from a light scattering solid to a liquid, the first polymer being dispersed in a matrix provided by a second polymer to form a light scattering polymer material when cold and a less or non-light scattering material when hot; and thermally reversible light scattering materials which go from light scattering at lower temperatures to less or non-light scattering at higher temperatures. The thermally reversible light scattering materials of the invention can be incorporated in many applications including a window which can reversibly change from a privacy condition to a non-privacy or clear condition; a window which can reversibly change between displaying images or objects to obscuring images or objects; a layer which can reversibly change between being clear and frosted by cycling the temperature of the layer; a reversible display; a temperature indicating material or device.

G02F 101
US Classification:
521733, 527861, 521713, 359265, 359275, 252581
Abstract:
The invention is an energy efficient, thermochromic device that may be used to allow sunlight or solar radiation into a building or structure when the ambient temperature is low and substantially blocks solar radiation when the ambient temperature is high, especially when sunlight is directly on the window.

Ligand Exchange Thermochromic, (Letc), Systems

US Patent:
2008010, May 1, 2008
Filed:
Sep 4, 2007
Appl. No.:
11/849574
Inventors:
Harlan Byker - West Olive MI,
Paul Ogburn - Hudsonville MI,
Douglas Griend - Grand Rapids MI,
Brad Veldkamp - Zeeland MI,
Derick Winkle - Holland MI,
Assignee:
PLEOTINT, LLC - West Olive MI
International Classification:
G02F 1/17
US Classification:
359288000
Abstract:
Ligand exchange of thermochromic, LETC, systems exhibiting a reversible change in absorbance of electromagnetic radiation as the temperature of the system is reversibly changed are described. The described LETC systems include one or more than one transition metal ion, which experiences thermally induced changes in the nature of the complexation or coordination around the transition metal ion(s) and, thereby, the system changes its ability to absorb electromagnetic radiation as the temperature changes.

Multi-Layer Ligand Exchange Thermochromic Systems

US Patent:
2008010, May 1, 2008
Filed:
Sep 4, 2007
Appl. No.:
11/849659
Inventors:
Harlan Byker - West Olive MI,
Frederick Millett - Grand Haven MI,
Paul Ogburn - Hudsonville MI,
Douglas Vander Griend - Grand Rapids MI,
Brad Veldkamp - Zeeland MI,
Derick Winkle - Holland MI,
Assignee:
PLEOTINT, LLC - West Olive MI
International Classification:
G02F 1/17
US Classification:
359288000
Abstract:
Ligand exchange of thermochromic, LETC, systems exhibiting a reversible change in absorbance of electromagnetic radiation as the temperature of the system is reversibly changed are described. The described LETC systems include one or more than one transition metal ion, which experiences thermally induced changes in the nature of the complexation or coordination around the transition metal ion(s) and, thereby, the system changes its ability to absorb electromagnetic radiation as the temperature changes. In accordance with one aspect of the present invention, a thermochromic device is disclosed comprising at least two thermochromic layers when each thermochromic layer includes a polymer, at least one transition metal ion, at least one HεL ligand capable of forming a HεMLC with the transition metal ion and at least one LεL ligand capable of forming an LεMLC with the transition metal ion. In accordance with yet another aspect of the present invention, the thermochromic device further includes a separator between the first and second thermochromic layers to prevent intermixing of the contents of the layers.

Ligand Exchange Thermochromic Systems And High E Ligands For Same

US Patent:
2008010, May 8, 2008
Filed:
Sep 4, 2007
Appl. No.:
11/849624
Inventors:
Harlan Byker - West Olive MI,
Paul Ogburn - Hudsonville MI,
Douglas Griend - Grand Rapids MI,
Brad Veldkamp - Zeeland MI,
Derick Winkle - Holland MI,
Assignee:
PLEOTINT, LLC - West Olive MI
International Classification:
G01K 11/16
US Classification:
252408100
Abstract:
Ligand exchange of thermochromic, LETC, systems exhibiting a reversible change in absorbance of electromagnetic radiation as the temperature of the system is reversibly changed are described. The described LETC systems include one or more than one transition metal ion, which experiences thermally induced changes in the nature of the complexation or coordination around the transition metal ion(s) and, thereby, the system changes its ability to absorb electromagnetic radiation as the temperature changes. In accordance with certain aspects of the present invention, a thermochromic system is disclosed comprising a transition metal ion and a ligand wherein the ligand comprises a nitrogen-containing five or six membered heterocyclic compound that coordinates through the nitrogen atom to the transition metal ion in a HεMLC formed between the transition metal ion and the ligand. In accordance with other aspects of the present invention, thermochromic systems are disclosed comprising a transition metal ion with particularly useful ligands, such as phosphine compounds, tridentate ligands that coordinate through three nitrogen atoms, bidentate ligands, or ortho hindered pyridine monodentate ligands.
