摘要:
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.

The invention relates to a method for the production of micro- and/or nanopore mass arrangements on a substrate including functionalization of the substrate surface in selected areas; deposition of colloidal particles that have the capacity to selectively bond to the functionalized areas of the substrate surface from an aqueous dispersion on the substrate surface, during which an ordered monolayer of the particles forms on the substrate surface; separation of non-bound colloidal particles; freezing of the substrate; and sublimation of the residual water on the substrate in the vacuum, during which the short-range order of the particle monolayer is preserved.

The invention relates to a method for producing an anti-reflection surface on an optical element, said method comprising the following steps: a) the optical element is prepared; b) uncharged, spherical, micellar polymer units comprising an inner core region and an outer shell region are prepared; and c) at least one region of the surface of the optical element is coated with polymer units in such a way that the polymer units are essentially regularly dispersed in a film-type layer over the surface of the optical element. The invention also relates to an optical element having an anti-reflection surface (28a, 28b, 28c) comprising spherical micellar polymer units (16a, 16b, 16c) having an inner core region (18) and an outer shell region (20) and being essentially regularly dispersed in a film-type layer (26a, 26b, 26c) over the surface of the optical element (22). The invention further relates to an optical element having an anti-reflection surface (34, 34a) comprising metal clusters (32, 32a) and/or metal oxide clusters (38, 38) which are essentially regularly distributed over the surface of the optical element (22).
摘要:
Ultralyophobe interfaces that are substantially inert to contaminants, thereby resulting in surfaces that are hydrophobic and/or lyophobic. The substrates include a substrate surface and have a bonding layer and a plurality of flexible fibers bound to the bonding layer. The flexible fibers have an elastic modulus and an aspect ratio, wherein as the elastic modulus of the fiber increases, the aspect ratio increases such that the flexible fibers bend upon contact of a liquid surface.

Stellate polymers containing hydrophilic polymer arms, which bear reactive functional groups on their free ends, are useful for producing ultra-thin coatings that form hydrogels. Such coatings actively suppress an unspecific protein absorption on surfaces provided with such coatings.
