Definitions
- the invention relates to antimicrobial coatings which are obtained by graft copolymerization of acrylic-substituted alkylsulfonic acids, optionally with further monomers, on a substrate, to a process for their preparation and their use.
- Bacteria must be kept away from all areas of life where hygiene is important. This affects textiles for direct body contact, especially for the genital area and for nursing and elderly care. In addition, bacteria must be kept away from furniture and device surfaces in care stations, in particular in the area of intensive care and the care of small children, in hospitals, in particular in rooms for medical interventions and in isolation stations for critical infections and in toilets.
- the copolymer produced with aminomethacrylates is only a matrix or carrier substance for added microbicidal active substances which can diffuse or migrate from the carrier substance.
- Polymers of this type lose their effect more or less quickly when the necessary “minimum inhibitory concentration” (M-K) is no longer achieved on the surface.
- the object of the present invention is therefore to develop novel, antimicrobial polymers. As a coating, these should prevent the settlement and spread of bacteria on surfaces.
- R 5 substituted or unsubstituted, branched or unbranched aliphatic or aromatic hydrocarbon radical with 1 to 50 carbon atoms

- the homo- or copolymerization is expediently carried out by a radical initiator or by radiation-induced radiation. Typical procedures are described in the examples.
- the antimicrobial coatings according to the invention can also be obtained by copolymerizing monomers of the formula I with at least one aliphatic unsaturated monomer on a substrate. A physisorbed coating of the antimicrobial copolymer is obtained on the substrate. An analogous procedure also applies to the coatings consisting of the homopolymer of monomers of the formula I.
- All polymeric plastics are suitable as substrate materials.
- the method according to the invention can also be used on surfaces of lacquered or otherwise with plastic Use coated metal, glass or wooden bodies.
- the coatings can be obtained by graft polymerization of a substrate with monomers of the formula I and / or, optionally, with at least one aliphatic unsaturated monomer.
- the grafting of the substrate enables the antimicrobial coating to be covalently bound to the substrate. All polymeric materials, such as the plastics already mentioned, can be used as substrates for a graft polymerization.
- the substrates can be activated by UV radiation in the wavelength range 170-400 nm, preferably 170-250 nm.
- a suitable radiation source is e.g. B a UV excimer device HERAEUS Noblelight, Hanau, Germany.
- mercury vapor lamps are also suitable for substrate activation if they emit significant amounts of radiation in the areas mentioned.
- the exposure time is generally 0.1 seconds to 20 minutes, preferably 1 second to 10 minutes.
- Corona devices (SOFTAL, Hamburg, Germany) can also be used for activation.
- the exposure times in this case are usually 1 to 10 minutes, preferably 1 to 60 seconds.
- Activation by electrical discharge, electron or ⁇ -rays (e.g. from a cobalt 60 source) and ozonization enable short exposure times, which are generally 0.1 to 60 seconds.
- graft polymerization can also be achieved by a process which is described in European patent application 0 872 512 and is based on a graft polymerization of swollen monomer and initiator molecules. Both component I and component II can be used for swelling.
- the components can be applied to the substrate in solution.
- Suitable solvents are, for example, water, ethanol, methanol, methyl ethyl ketone, diethyl ether, dioxane, Hexane, heptane, benzene, toluene, chloroform, dichloromethane, tetrahydrofuran and acetonitrile.
- Component II can also serve as solvent for component I.
- the solution of the polymers can e.g. B. by dipping, spraying or painting on the substrates.
- the present invention further relates to the use of the antimicrobial coatings according to the invention for the production of antimicrobially active products and the products thus produced as such.
- the products can contain or consist of modified polymer substrates according to the invention.
- modified polymer substrates according to the invention are preferably based on polyamides, polyurethanes, polyether block amides, polyester amides or imides, PVC, polyolefins, silicones, polysiloxanes, polymethacrylate or polyterephthalates, the surfaces modified with polymers according to the invention exhibit.
- Antimicrobial products of this type are, for example, and in particular machine parts for food processing, components of air conditioning systems, roofing, bathroom and toilet articles, kitchen articles, components of sanitary facilities, components of animal cages and houses, toys, components in water systems, food packaging, operating elements (touch panel ) of devices and contact lenses.
- the coatings according to the invention made from the homo- or copolymers or corresponding graft polymers of the monomers of the formula I, optionally with further aliphatic monomers, can be used wherever it is possible to use bacteria-free, ie. H. microbicidal surfaces or surfaces with non-stick properties.
- bacteria-free ie. H. microbicidal surfaces or surfaces with non-stick properties.
- examples of uses for the coatings according to the invention are, in particular, paints, protective coatings or coatings in the following areas:
- Marine hulls, port facilities, buoys, drilling platforms, ballast water tanks House: roofs, cellars, walls, facades, greenhouses, sun protection, garden fences, wood protection - Sanitary: Public toilets, bathrooms, shower curtains, toiletries, swimming pool, sauna, joints, sealing compounds
- Medical technology contact lenses, diapers, membranes, implants
