rüstung.are built up in what
A represents an optionally substituted C₁-C₄ alkylene radical,
and the manufacture of coatings from these polythiophenes on plastic or glass for antistatic equipment.
Aus EP-A 440 957 sind bekannt lösliche Salze von Poly thiophenen, die aus Struktureinheiten der Formel (II)Soluble salts of poly are known from EP-A 440 957 thiophenes consisting of structural units of the formula (II)
aufgebaut sind, worin
R¹ und R² unabhängig voneinander Wasserstoff oder C₁-C₄-
Alkyl und zusammen einen gegebenenfalls
substituierten C₁-C₄-Alkylenrest bedeuten
und von Polyanionen sowie die Herstellung von Überzügen
aus diesen Salzen auf Kunststoffen oder Glas zur anti
statischen Ausrüstung.are built up in what
R¹ and R² independently of one another are hydrogen or C₁-C₄-alkyl and together represent an optionally substituted C₁-C₄-alkylene radical
and of polyanions and the production of coatings from these salts on plastics or glass for anti-static finishing.
Der Erfindung liegt die Erkenntnis zugrunde, daß die Polythiophene gemäß DE-OS 38 13 589 und EP-A 440 957 auch hervorragende IR-Absorber sind und daher zur Her stellung von Wärmeschutzscheiben dienen können.The invention is based on the knowledge that the Polythiophenes according to DE-OS 38 13 589 and EP-A 440 957 are also excellent IR absorbers and therefore for manufacture position of heat shields can serve.
Eine Anwendung von Wärmeschutzscheiben ist die Verwen dung als Wärmeschutzfenster. Wärmeschutzfenster, die durch Absorption oder Reflexion Wärmestrahlung ab schirmen, sind bekannt. So hat man Glas- und Kunst stoffscheiben mit Metallen oder Metalloxiden bedampft. Solche Scheiben schirmen zwar IR-Strahlung ab, absorbie ren aber auch große Teile des sichtbaren Lichtes. Der wesentliche Vorteil der erfindungsgemäß angewendeten Polythiophene liegt darin, daß mit ihnen beschichtete Glas- und Kunststoffflächen zwar IR-Strahlung ab schirmen, sichtbares Licht aber fast vollständig durchlassen. One application of heat shields is the use as a heat protection window. Thermal windows, the heat absorption by absorption or reflection shield, are known. So you have glass and art cloth discs coated with metals or metal oxides. Such panes shield IR radiation, but absorb but also large parts of the visible light. Of the essential advantage of the applied according to the invention Polythiophene is that coated with them Glass and plastic surfaces from IR radiation shield, visible light but almost completely let through.
Gegenstand der Erfindung ist somit die Verwendung von durchsichtigen Kunststoff- und Glasscheiben, die mit Polythiophenen oder löslichen Polythiophensalzen, enthaltend wiederkehrende Struktureinheiten der Formel (III)The invention thus relates to the use of clear plastic and glass panes with Polythiophenes or soluble polythiophene salts, containing recurring structural units of the formula (III)
mit
R¹ und R² Wasserstoff, C₁-C₄-Alkyl oder R¹ und
zusammen gegebenenfalls substituiertes C₁-C₄-
Alkylen
beschichtet sind, als Wärmeschutzscheiben.With
R¹ and R² are hydrogen, C₁-C₄-alkyl or R¹ and together optionally substituted C₁-C₄-alkylene
are coated as heat shields.
Insbesondere sind Polythiophene mit Struktureinheiten der Formel (III) geeignet, in denen R¹ und R² unabhängig voneinander Wasserstoff oder Methyl, oder zusammen einen gegebenenfalls alkylsubstituierten Methylenrest, einen gegebenenfalls durch C₁-C₁₂-Alkyl- oder Phenyl-substi tuierten Ethylen-1,2-Rest oder einen Cyclohexylen-1,2- Rest, darstellen.In particular, polythiophenes with structural units of formula (III) in which R¹ and R² are independent from each other hydrogen or methyl, or together one optionally alkyl substituted methylene, one optionally by C₁-C₁₂ alkyl or phenyl substi tuated ethylene 1,2 residue or a cyclohexylene 1,2 Rest, represent.
Die Herstellung der Polythiophene und die Herstellung von Überzügen aus den Polythiophenen ist in der DE-OS 38 13 589 und der EP-A 440 957 ausführlich beschrieben. The production of the polythiophenes and the production of coatings from the polythiophenes is in DE-OS 38 13 589 and EP-A 440 957 described in detail.
Zur Anwendung als Wärmeschutzscheiben werden die Be schichtungen bevorzugt auf Glasscheiben oder Kunststoff scheiben oder Folien, beispielsweise aus Polycarbonat oder Polymethylmethacrylat, aufgebracht. Die Dicke der Beschichtung ist im allgemeinen 0,1 bis 50 µm, bevorzugt 0,2 bis 10 µm.The Be layers preferably on glass panes or plastic discs or foils, for example made of polycarbonate or polymethyl methacrylate. The thickness of the Coating is generally 0.1 to 50 µm, preferred 0.2 to 10 µm.
Zum Schutz vor mechanischen Verletzungen können die Be schichtungen aus Polythiophen mit transparenten Schutz schichten aus organischen oder anorganischen Polymeren abgedeckt werden. Geeignet sind hierzu lösliche ver netzende oder thermoplastische Lacke, z. B. auf Acrylat- oder Polyurethanbasis, sowie auch UV- oder elektronen strahlvernetzbare Produkte.To protect against mechanical injuries, the Be layers of polythiophene with transparent protection layers of organic or inorganic polymers be covered. Soluble ver wetting or thermoplastic lacquers, e.g. B. on acrylate or polyurethane base, as well as UV or electrons beam cross-linkable products.
Die Beschichtungen mit Polythiophenen haben sich in der Praxis als gegen UV-Strahlung sehr beständig erwiesen, so daß IR-Strahlen dauerhaft abgeschirmt werden.The coatings with polythiophenes have in the Practice proven to be very resistant to UV radiation so that IR rays are permanently shielded.
Eine klare transparente Polycarbonatfolie einer Dicke von 125 µm wird mit einer Lösung aus 0,9 g Polyvinyl acetat und 2,0 g Eisen-III-toluolsulfonat in einem Gemisch aus 10 g Aceton und 5 g Isopropanol mit einem Handcoater beschichtet (Naßfilmdicke ca. 24 µm). Die Beschichtung wird bei Zimmertemperatur 1 Stunde ge trocknet. Anschließend wird die Folie 10 Sekunden in eine 5%ige Lösung von 3,4-Ethylendioxythiophen in 5% Cyclohexan getaucht. Das Lösungsmittel wird bei 20°C abgedampft. Nach 24 Stunden bei 20°C wird die Folie mit fließendem Wasser gewaschen, um die in der Beschichtung enthaltenen Eisen-III-Salze zu entfernen und erneut ge trocknet.A clear transparent polycarbonate film of a thickness of 125 microns with a solution of 0.9 g of polyvinyl acetate and 2.0 g of ferric toluene sulfonate in one Mixture of 10 g acetone and 5 g isopropanol with a Handcoater coated (wet film thickness approx. 24 µm). The Coating is carried out at room temperature for 1 hour dries. Then the slide is in 10 seconds a 5% solution of 3,4-ethylenedioxythiophene in 5% Cyclohexane dipped. The solvent is at 20 ° C evaporated. After 24 hours at 20 ° C, the film is with running water washed to the in the coating remove iron III salts contained and ge again dries.
Die so beschichtete Folie absorbiert Infrarotstrahlung (Wellenlänge <800 µm) stark, während sichtbares Licht (Wellenlänge 400 bis 800 µm) nahezu ungehindert passiert.The film coated in this way absorbs infrared radiation (Wavelength <800 µm) strong, while visible light (Wavelength 400 to 800 µm) almost unhindered happens.
