The first and second polymer blocks are removed from the first film and oriented structures remain in the trough normal to the sidewalls and parallel to the surface layer. A second film of a second copolymer is coated inside the trough. Line-forming microdomains are assembled of the second copolymer, and form second self-assembled structures within the second film oriented normal to the oriented structures and parallel to the sidewalls. The third and fourth polymer blocks are removed, and at least one second oriented structure remains.09-25-2008

20080199646Inline Particle Deposition Extrusion - A process for altering the properties of extruded tubing by applying a solid particulate material to a tacky outer surface of the tubing as the tubing exists the extrusion head or die and prior to the tubing entering a cooling system of the extrusion line. The particulate material may act as a tie layer to improve the adherence of a second material to the outer surface of the extruded tubing, thus altering the tensile strength, elongation, and/or stiffness properties of the extruded tubing. In addition, the application of particulate material may be chosen to provide radiopacity to the extruded tubing. The solid particulate material may be deposited on the extruded tubing by vacuum deposition, magnetism, or pressurized means.08-21-2008
