Embodiment Construction

[0129] figure 1 An exemplary embodiment of a composite material 1 according to the invention is schematically shown. In the exemplary embodiment, the composite material 1 includes a substrate 2 , here in the form of a plastic substrate. A porous glass layer 3 is deposited on the top side of the substrate 2 by means of PVD. Porous glass layer 3 has a thickness of between 100 nm and 600 nm in the exemplary embodiment. Composite 1 is suitable for a large number of applications.

[0130] figure 2Another exemplary embodiment of a composite material 1 according to the invention is schematically shown. The composite material 1 comprises a substrate 2 consisting of a polymer material. A 100 nm to 500 nm thick porous glass layer 3 with a porosity of between 10% and 30% is deposited on the substrate by means of an electron beam evaporation method, and the porous glass layer 3 is then sealed with a sealing layer 4 . In this exemplary embodiment, the sealing layer is coated with t...

Abstract

The invention relates to a method for applying a porous glass layer. According to the invention, a porous glass layer is to be applied according to a PVD-method. The degree of porosity and average pore size can vary according to the process parameters, such as pressure and precipitation rate and by targeted addition of foreign bodies.

Description

Contents of the invention [0001] The invention relates to a method for applying a porous glass layer and a composite material comprising a porous glass layer. Background technique [0002] The production of porous glass layers on substrates is known. For example EP 708061 (Yazawa et al.) describes the production of porous glass layers by etching. [0003] The known etching methods for producing porous glass layers have the disadvantage that they are expensive. For example, multiple method steps are required to produce a porous glass layer. On the other hand, the porosity of the glass layer cannot be adjusted arbitrarily. Furthermore, the porosity of etched glass layers is generally not very homogeneous, and generally the porosity of the layers decreases with increasing depth. Thicker layers cannot be produced by etching either. Contents of the invention [0004] It is an object of the invention to provide a method for applying at least one porous glass layer which is ...
