20090155562 | Method for Producing Composite Materials - The present invention relates to a process for the preparation of composites from thermoplastic polymers and (semi)metal oxides, in particular silicon dioxide, wherein at least a part of the (semi)metal oxides is dispersed in the polymers in nanodispersed manner (nanocomposites). The invention relates to the composites obtainable by this process and their processing to give molded articles. | 06-18-2009 |
20090221202 | COMPOSITE MATERIALS CONTAINING HYDRAULIC BINDERS - The invention relates to novel composite materials, which comprise at least one thermoplastic organic polymer matrix and at least one hydraulic binder distributed in the polymer matrix. The invention also relates to a process for the preparation of such composite materials and to the use of these composite materials in textile materials. The composite materials comprise at least one thermoplastic organic polymer matrix and at least one hydraulic binder distributed in the polymer matrix, where the thermoplastic polymer matrix consists predominantly, i.e. to at least 60% by weight, in particular to at least 70% by weight, preferentially to at least 80% by weight, and especially preferred to at least 90% by weight, of at least one polymer, which is water-soluble or which under alkaline conditions is converted into a water-soluble polymer. | 09-03-2009 |
20090308842 | PHOTOCHEMICAL METHOD FOR MANUFACTURING NANOMETRICALLY SURFACE-DECORATED SUBSTRATES - The present invention relates to a photochemical method for manufacturing nanometrically surface-decorated substrates, i.e. the creation of periodic and aperiodic patterns of highly ordered inorganic nanostructures on a substrate. This method is based on the selective photochemical modification of a self-assembled monolayer of metal compound loaded polymer core-shell systems on widely variable substrates. Light exposure through an appropriate mask causes selective chemical modification of the polymer core shell system. By subsequently placing the substrate in an appropriate chemical solution that eradicates the non-modified polymer, the pattern given by the used mask is reproduced on the surface. Finally, the remaining organic matrix is removed and metal salt is transformed to the single metal or metal oxide nanodots by means of gas plasma treatment. | 12-17-2009 |
