Abstract
Composites, preferably fiber composite materials or composite coatings, preferably paint coatings comprise (A) a matrix material, and (B) microcapsules comprising a shell material consisting of a cell wall and/or a cell membrane, where the shell material of the microcapsules consists of a yeast cell, and one or more active substances included in the shell material, where the active substances consist of e.g. dyes, messengers, corrosion inhibitors, catalysts, solvents, thickeners, adhesion-reducing substances, de-icing reagents, and antimicrobial substances. Composites, preferably fiber composite materials or composite coatings, preferably paint coatings comprise (A) a matrix material, and microcapsules comprising a shell material consisting of a cell wall and/or a cell membrane, where the shell material of the microcapsules consists of a yeast cell, and one or more active substances included in the shell material, where the active substances consist of dyes, messengers, corrosion inhibitors, catalysts, solvents, thickeners, adhesion-reducing substances, de-icing reagents, antimicrobial substances, slip additive, lubricants and components for self-healing systems, the microcapsules have an average diameter of 10, preferably 20-150 mu m, the shell material further consists of a sporoderm of a pollen grain, preferably at least one exine sporoderm, and the shell material is partially covalently bonded to the matrix material. Independent claims are included for: (1) a coating material, preferably paint or adhesive for producing a coating, comprising (A) and (B); (2) producing a coating material, comprising (i) providing one or more binding agents, preferably consisting of epoxy resins, polyurethanes, acrylates, alkyd resins, formaldehyde condensation resins, polyesters, polyethers, polyethylene and PVC, (ii) providing the microcapsules, and mixing the microcapsules from step (ii) with the binder agents from the step (i) and optionally with other ingredients; (3) a component comprising the composite material, preferably the fiber composite material; (4) a product comprising a substrate and the coating applied on a surface portion of the substrate, where the substrate consists of metals and alloys, preferably light metal, silicate glasses such as slices or ceramics, organic surfaces, bones, teeth, wood, laminates, polymers and fiber-reinforced polymers, casting resins, fibers such as glass, carbon, aramid and natural fibers, leather, fabrics, paper and cardboard; and (5) improving the corrosion resistance of a metal, comprising applying the coating material according onto the surface of the metal, where the active substances in the shell material are corrosion inhibitors.
