The invention relates to an antimicrobial layer material comprising a layer with a particulate biocidal active ingredient and, on top of that, a layer as transport control layer, wherein the transport control layer is depositable or has been deposited in an afterglow PE-CVD method. The invention further relates to a substrate coated with such an antimicrobial layer material, to the use of a plasma-polymeric layer deposited in an afterglow PE-CVD method as transport control layer for a particulate biocidal active ingredient, and to a method of producing an antimicrobial layer material and to a method of producing a substrate comprising an antimicrobial layer material.

Antimicrobial layered material

The invention relates to a solid plasma polymer body, especially a plasma polymer layer, which has an exceptionally high modulus of elasticity at a given C/O ratio. It further relates to a solid body comprising a substrate and, applied to this substrate, a plasma polymer layer of the invention.

Solid plasma polymer body

The invention relates to a composite comprising (i) a plastics component or (ii) a semifinished plastics product with a protective layer system, where the protective layer system comprises a plastics film and an organosilicon plasma polymer layer, the organosilicon plasma polymer layer is arranged between the (i) plastics component or the (ii) semifinished plastics product and the plastics film and, after the hardening of the (i) plastics component or of the (ii) semifinished plastics product, the organosilicon plasma polymer layer adheres more securely to the plastics film than to the (i) plastics component or the (ii) semifinished plastics product.

Assembly with temporary protective film

Siliconized release film for the production of polymer moldings from fiber composites using a mold, which comprises a support film which is capable of vacuum deep drawing at room temperature and a coating which can be applied in liquid form and consists, optionally after removal of any solvent, of more than 90 atom % of silicon, carbon and/or oxygen, more than 45 atom % of carbon and more than 20 atom % of silicon, in each case based on the total coating and measured by XPS, characterized in that the coating has been crosslinked by means of condensation reactions, addition reactions or radiation.

Silicone-coated release film with a special vacuum deep drawing capability

The invention relates to an antimicrobial and non-cytotoxic coating material and to uses of said coating material.

Coating material

The present invention relates to the use of a crosslinked, silicon-containing layer containing, substantially consisting of or consisting of silicon, O, C, H, optionally N which can be produced by plasma polymerization and/or crosslinking of organosilicon liquids by a plasma process and/or UV radiation of a wavelength of less than 250 nm, without using metals of an atomic number of more than 14, as a biocompatible surface, for imparting to a surface or providing a surface with a non-genotoxic effect. The invention also relates to correspondingly coated articles and to processes for the production thereof.

Biocompatibility layer and coated objects

The present invention concerns items that contain or consist of a plasma polymer product, consisting of carbon, silicon, oxygen and hydrogen, wherein the ESCA spectrum of the plasma polymer product, with calibration to the aliphatic portion of the C 1s peak at 285.00 eV, in comparison with a trimethylsiloxy-terminated polydimethylsiloxane (PDMS) with a kinematic viscosity of 350 mm/s at 25&#xb0; C. and a density of 0.97 g/ml at 25&#xb0; C., the Si 2p peak has a bond energy that is shifted by 0.44 eV, at most, to higher or lower bond energies, and the O 1s peak has a bond energy that is shifted by 0.50 eV, at most, to higher or lower bond energies.

Flexible plasma polymer products, corresponding items and use thereof

The invention relates to a metal substrate with a corrosion-resistant coating produced by means of plasma polymerization, wherein the substrate is subjected to mechanical, chemical and/or electrochemical smoothing in a pre-treatment step and is subsequently exposed to a plasma at a temperature of less than 200&deg; C. and at a pressure of 10 bis 100 mbars, whereby in a first step the surface is activated in a reducing plasma and in a second step the polymer is separated from a plasma containing at least one hydrocarbon or silico-organic compound which can be vaporized in plasma conditions, optionally contains oxygen, nitrogen or sulphur and can contain fluorine.
