  • Patent number: 8399058
    Abstract: The present disclosure relates to a profiled masking article and method of masking a substrate to be treated or painted that provides a feathered or soft edge between painted and unpainted areas. The masking article described herein may be used as a single strip, or as multiple strips, placed side by side, wherein a strip is removed between treatments of different types. This allows successive treatment layers to completely cover previous layers, thus avoiding defects resulting from exposed layers of material. In an embodiment, the present disclosure is directed to a masking article comprising: at least one elongate body (12), said body (12) having a top surface, a bottom surface and at least two lateral surfaces, wherein at least a portion of said body comprises an adhesive material; and a generally planar top portion (14), connected to the body along at least one surface, said top portion (14) having a microstructured surface.

  • Patent number: 8389055
    Abstract: A process for preparing a metal nanostructure having metal masses with zero valence aligned on a substrate surface wherein the size and shape of the metal masses are controlled is described. The process can include preparing a micro phase separation membrane of an amphiphilic block copolymer on a substrate and then exposing the membrane to a solution containing metal ions; drying the membrane to form a micro phase separation membrane with the metal ions localized in hydrophilic segments of the membrane; and irradiating vacuum ultraviolet light on the membrane to reduce the metal ions and to remove organic materials.
