Description
Die Erfindung betrifft ein Verfahren zur Herstellung von Mehrschichtsystemen mit photokatalytischen Eigenschaften auf Oberflächen.The The invention relates to a method for producing multilayer systems with photocatalytic properties on surfaces.
PVD – Verfahren (Physical vapor deposition) wie Verdampfungs- und Zerstäubungsprozesse sind seit langem Stand der Technik. Das Sputtern oder (Festkörper-)Zerstäuben bezeichnet den Prozess, bei dem Atome eines Materials durch den Beschuss mit hochenergetischen Edelgasionen aus dem Verbund herausgeschlagen und auf einem Substrat abgeschieden werden. Hierzu existiert eine umfangreiche Standardliteratur, von der exemplarisch das Diodensputtern (K. Wasa, S. Hayakawa: "HANDBOOK OF SPUTTER DEPOSITION TECHNOLOGY: PRINCIPLES, TECHNOLOGY, AND APPLICATIONS" (MATERIALS SCIENCE AND PROCESS TECHNOLOGY SERIES) (1992)) erwähnt werden soll.PVD method (Physical vapor deposition) such as evaporation and sputtering processes have long been state of the art. The sputtering or (solid) sputtering designates the process by which atoms of a material are hit by the bombardment high-energy noble gas ions knocked out of the composite and deposited on a substrate. For this exists a extensive standard literature, exemplified by the diode sputtering (K. Wasa, S. Hayakawa: "HANDBOOK OF SPUTTER DEPOSITION TECHNOLOGY: PRINCIPLES, TECHNOLOGY, AND APPLICATIONS "(MATERIALS SCIENCE AND PROCESS TECHNOLOGY SERIES) (1992)).

Der Erfindung liegt die Aufgabe zugrunde, ein Verfahren anzugeben, das die bestehenden Nachteile der etablierten Verfahren zur Abscheidung photokatalytischer Schichten überwindet.Of the Invention has for its object to provide a method which the existing disadvantages of the established methods of deposition photocatalytic layers overcomes.
Erfindungsgemäß wird diese Aufgabe bei einem Verfahren zum Beschichten von Substraten mit einem photokatalytisch aktiven Schichtsystem dadurch gelöst, dass mindestens eine Schicht durch ein Flammenpyrolyse-Verfahren aufgebracht wird, während die anderen Schichten vorzugsweise durch physikalische Gasphasenabscheidung hergestellt werden. Der wesentliche Vorteil der Erfindung besteht in der Kombination von flammenpyrolytischer Abscheidung von Siliziumoxidschichten und dem nachfolgenden Aufbringen der eigentlichen photokatalytischen Titanoxidschicht mittels Festkörperzerstäubung. Die Siliziumoxidschichten dienen dabei als Barriere gegenüber der Diffusion von Alkaliionen aus dem Glassubstrat in die photokatalytische Schicht. Gleichzeitig bedingt die innere Struktur der flammenpyrolytischen Schichten eine ausgesprochen hydrophile Oberfläche. Ein weiterer Vorteil der Erfindung besteht darin, dass der Temperatureintrag während der Herstellung, bedingt durch die beiden Abscheideverfahren Flammenpyrolyse und Festkörperzerstäubung, deutlich niedriger ist. Die erfindungsgemäß hergestellten Schichtsysteme zeichnen sich dadurch aus, dass durch eine Nachtemperung die photokatalytischen Abbauraten um ein Vielfaches erhöht werden.According to the invention this Task in a process for coating substrates with a photocatalytic active layer system solved by at least one layer is applied by a flame pyrolysis method while the other layers, preferably by physical vapor deposition getting produced. The main advantage of the invention is in the combination of flame pyrolytic deposition of silicon oxide layers and the subsequent application of the actual photocatalytic Titanium oxide layer by means of solid atomization. The Silicon oxide layers serve as a barrier to the Diffusion of alkali ions from the glass substrate into the photocatalytic layer. At the same time, the internal structure of the flame pyrolytic causes Layers a pronounced hydrophilic surface. Another advantage of Invention is that the temperature entry during manufacture, due to the two deposition methods flame pyrolysis and Solid-state atomization, clearly is lower. The inventively produced Layer systems are characterized by the fact that by a Nachemperung the photocatalytic degradation rates are increased many times over.
Die Erfindung soll nachstehend anhand von Ausführungsbeispielen näher erläutert werden. Die Zeichnungen zeigen:The Invention will be explained below with reference to exemplary embodiments. The drawings show:
Das erfindungsgemäße Verfahren ist gerichtet auf die Herstellung eines Mehrschichtsystems basierend auf SiO2-x(OH)2x mit x von 0 bis 2 (nachfolgend Siliziumoxidschicht) und Titanoxid. Eine nachfolgende thermische Behandlung der Beschichtung ist in Abhängigkeit vom verwendeten Substrat zur Steigerung des photokatalytischen Effekts möglich.The inventive method is directed to the production of a multi-layer system based on SiO 2-x (OH) 2x with x from 0 to 2 (hereinafter silicon oxide layer) and titanium oxide. A subsequent thermal treatment of the coating is possible depending on the substrate used to increase the photocatalytic effect.
Inhalt der erfindungsgemäßen Lösung ist die Kopplung einer Siliziumoxidschicht mit einer Titanoxidschicht. Diese Titanoxidschicht wird hierbei entweder direkt auf die Siliziumoxidschicht oder auf ein aus mehreren zusätzlichen Schichten bestehendes Mehrschichtsystem, welches die Siliziumoxidschicht beinhaltet, aufgebracht. Die Siliziumoxidschicht wird dabei flammenpyrolytisch abgeschieden. Die Titanoxidschicht wird anschließend durch Festkörperzerstäubung aufgebracht. Für eine flammenpyrolytische Abscheidung der Siliziumoxidschichten werden als Precursorsubstanzen metallorganische Verbindungen, welche Silizium enthalten, verwendet.content the solution according to the invention the coupling of a silicon oxide layer with a titanium oxide layer. This titanium oxide layer is in this case either directly on the silicon oxide layer or one of several additional ones Layers existing multi-layer system, which is the silicon oxide layer includes, upset. The silicon oxide layer becomes flame-pyrolytic deposited. The titanium oxide layer is subsequently applied by solid-state atomization. For one flame pyrolytic deposition of the silicon oxide layers as precursor substances organometallic compounds which silicon included, used.
Die Schichtdicke der Siliziumoxidschicht kann 5 bis 200 nm, bevorzugt jedoch 10 bis 30 nm, betragen.The Layer thickness of the silicon oxide layer may be 5 to 200 nm, preferably however, 10 to 30 nm.
Die Titanoxidschicht kann bei einer Prozesstemperatur von Raumtemperatur bis zu 500 °C abgeschieden werden. Die Schichtdicken besagter Titanoxidschichten können zwischen 5 nm und 300 nm betragen.The Titanium oxide layer can be at a process temperature of room temperature up to 500 ° C be deposited. The layer thicknesses of said titanium oxide layers can between 5 nm and 300 nm.
Eine abschließende Temperung kann in einem Temperaturbereich von 0 °C bis 650 °C durchgeführt werden. Die Dauer einer Temperung kann zwischen 0 h und 5 h betragen. Als Substrate können sowohl unbeschichtete, als auch bereits beschichtete Materialien dienen. Hierbei kann es sich um Einzelschichten, aber auch um Mehrschichtsysteme handeln. Das bevorzugte Substratmaterial ist Glas. Selbst Textilien sind als Substrate geeignet.A final Annealing can be carried out in a temperature range from 0 ° C to 650 ° C. The duration of a Annealing can be between 0 h and 5 h. As substrates both uncoated, as well as already coated materials are used. These can be single layers, but also multi-layer systems act. The preferred substrate material is glass. Even textiles are suitable as substrates.
Weiterhin ist es möglich Schichtsysteme mit photokatalytischen Eigenschaften herzustellen, bei denen sowohl die Siliziumschicht als auch Titanoxidschicht mitttels Festkörperzerstäubung abgeschieden werden.Farther Is it possible To produce coating systems with photocatalytic properties, in which both the silicon layer and titanium oxide mitttels Solids atomization deposited become.
