摘要:
The invention relates to a coating method for generating a functional layer on mechanically stressed components or surfaces, the method comprising the following steps: provision or application of a first material layer (2) made of a first material or substrate matrix (5) having a higher mechanical flexibility than a second material (6) onto a substrate (1) forming the component and/or the surface; structuring the first material layer (2) so that the material layer surface of the first material layer (2) facing away from the substrate (1) is provided with a three-dimensionally molded basic structure (14) having elevations (10) and depressions (12), and coating the material layer surface of the first material layer (2) with a second material layer (3) made of the second material (6) such that the second material layer (3) essentially assumes the basic structure (14) of the material layer surface having the elevations (16) and depressions (18). The invention further relates to surface layer structures that can be produced in this manner.

A releasable transfer film is suitable to provide a metalized embossed composite onto a paper substrate without a release layer between the composite and a polymeric carrier layer. The transfer film includes a polymeric base layer, an embossing material layer and a metal layer. The transfer film is bonded to the paper substrate with an adhesive layer allowing the polymeric barrier layer to peel away from and to expose the metal-backed, embossing material layer. The substrate covered with the metalized embossed composite can be used to impart holographic style images to packaging, printed media products such as magazines.

Surfaces having a hierarchical structure— having features of both microscale and nanoscale dimensions— can exhibit superhydrophobic properties and advantageous condensation and heat transfer properties. The hierarchical surfaces can be fabricated using biological nanostructures, such as viruses as a self-assembled nanoscale template.

Thermally stable polycrystalline constructions comprise a diamond body joined with a substrate, and may have a nonplanar interface. The construction may include an interlayer interposed between the diamond body and substrate. The diamond body preferably has a thickness greater than about 1.5 mm, and comprises a matrix phase of bonded together diamond crystals and interstitial regions disposed therebetween that are substantially free of a catalyst material used to sinter the diamond body. A replacement material is disposed within the interstitial regions. A population of the interstitial regions may include non-solvent catalyst material and/or an inf?ltrant aid disposed therein. The diamond body comprises two regions; namely, a first region comprising diamond grains that may be sized smaller than diamond grains in a second region, and/or the first region may comprise a diamond volume that is greater than that in the second region.

A multilayered formable packaging film and a method of manufacturing the film are disclosed. The film is suitable for making blisters either by thermoforming or cold forming. The visible surface of the film has unique features which prevent counterfeiting. These features are retained on the film even after blister formation.

Ultra-thin hybrid and/or microporous materials and methods for their fabrication are provided. In one embodiment, the exemplary hybrid membranes can be formed including successive surface activation and reaction steps on a porous support that is patterned or non-patterned. The surface activation can be performed using remote plasma exposure to locally activate the exterior surfaces of porous support. Organic/inorganic hybrid precursors such as organometallic silane precursors can be condensed on the locally activated exterior surfaces, whereby ALD reactions can then take place between the condensed hybrid precursors and a reactant. Various embodiments can also include an intermittent replacement of ALD precursors during the membrane formation so as to enhance the hybrid molecular network of the membranes.

Es wird vorgeschlagen ein Werkstück (10) mit einer Metalloxid-beschichteten Oberfläche (9) mit wählbarem Grad des hydrophoben Verhaltens herzustellen, indem die Oberfläche eines Substratmaterials (1) mindestens in Teilbereichen mit einer Mikrostruktur (2, 3) versehen wird durch mechanisches Prägen und anschliessend beschichtet wird. Im Anschluss an die Mikrostrukturierung wird eine kohlenwasserstoffhaltige oder siliziumoxidhaltige Schutzschicht (6) und / oder mindestens eine Deckschicht (7) abgeschieden an deren Oberfläche (9) die gewünschten hydrophoben Eigenschaften auftreten. Die keimtötende und katalytische Wirkung der metalloxidhaltigen Deckschicht (7) wird durch Inkorporation von metallhaltigen Nanopartikeln verstärkt oder erzeugt.

A method for high resolution ink-jet print using a pre-patterned substrate employs an ink-jet printing device including an ink-jet head for discharging conductive ink droplets and a driving stage for supporting a substrate to which the conductive ink droplets are hit, to draw a fine line width pattern on the substrate. The method includes (A) forming a stripe pattern with repeated stripes on a substrate surface on which a fine line width pattern will be formed, thereby preparing a pre-patterned substrate; (B) loading the substrate to the ink-jet printing device; and (C) injecting conductive ink droplets to a substrate region where the stripe pattern is formed. An equivalent interval (d) of the stripe pattern and a fine line width (D) of the drawn fine line width pattern satisfy a relation of d
