20100316960 | PATTERNING NANO-SCALE PATTERNS ON A FILM COMPRISING UNZIPPING POLYMER CHAINS - The invention concerns a method for patterning a surface of a material. A substrate having a polymer film thereon is provided. The polymer is a selectively reactive polymer (e.g. thermodynamically unstable): it is able to unzip upon suitable stimulation. A probe is used to create patterns on the film. During the patterning, the film is locally stimulated for unzipping polymer chains. Hence, a basic idea is to provide a stimulus to the polymeric material, which in turn spontaneously decomposes e.g. into volatile constituents. For example, the film is thermally stimulated in order to break a single bond in a polymer chain, which is sufficient to trigger the decomposition of the entire polymer chain. | 12-16-2010 |

20110199887 | METHOD AND DEVICE FOR HIGH DENSITY DATA STORAGE - The present invention is directed to a method for producing a data storage medium on a surface of a substrate for storing data in the form of topographic features. The method comprises a first step wherein a crosslinking agent containing at least three alkyne groups is deposited on the surface of the substrate. In a second step the deposited cross linking agent is cured so as to obtain the data storage medium in the form of a crosslinked polymeric layer on the surface of the substrate. The invention is further directed to a data storage medium obtained by this method and a data storage device comprising this data storage medium | 08-18-2011 |
