A microstructured article includes a nanovoided layer having opposing first and second major surfaces, the first major surface being microstructured to form prisms, lenses, or other features. The nanovoided layer includes a polymeric binder and a plurality of interconnected voids, and optionally a plurality of nanoparticles. A second layer, which may include a viscoelastic layer or a polymeric resin layer, is disposed on the first or second major surface. A related method includes disposing a coating solution onto a substrate. The coating solution includes a polymerizable material, a solvent, and optional nanoparticles. The method includes polymerizing the polymerizable material while the coating solution is in contact with a microreplication tool to form a microstructured layer. The method also includes removing solvent from the microstructured layer to form a nanovoided microstructured article.

The present invention relates to use of a polypropylene composition comprising a polypropylene having—a melt flow rate MFR2 (230° C./2.16 kg) measured according to ISO 1133 of 10 to 40 g/10 min, —a melting temperature T.sub.m as determined by DSC according to ISO 11357 of 149 to 160° C., and—a molecular weight distribution MWD of 2.4 to 4.5 as determined by GPC, for extrusion coating of an article, to a process for extrusion coating of an article and to an extrusion coated article.

A system for manufacturing structural members with coated main and side surfaces, the system comprising at least one structural member having at least one main surface; at least one side surface which is obliquely oriented relative to the main surface; and a coating apparatus operative, in a single pass over the structural member, to deposit at least one coating on said at least one structural member including said at least one main surface and said at least one side surface.

A system and method for coating an expandable member of a medical device comprising a support structure to support the expandable member and a dispenser positioned with at least one outlet proximate a surface of an expandable member. A drive assembly establishes relative movement between the at least one outlet and the surface of the expandable member to apply fluid on the surface of the expandable member along a coating path. A guide maintains a substantially fixed distance between the at least one outlet and the surface of the expandable member during relative movement therebetween by displacing the expandable member relative to the at least one outlet.

A composite fiber may include at least one reinforcing filament formed of a first material. A second material maybe systematically deposited in a printed onto the at least one reinforcing filament such that at least one of a length, a width, and a thickness of the second material varies across a surface of the at least one reinforcing filament. The printed pattern may alter one or more properties of a composite structure containing the composite fiber.
