Publication number: 20130150509Abstract: In a method of manufacturing TSSS and TISS coatings applied onto substrates of copper or aluminum, inorganic pigments are functionalized by aminosilane. The functionalized pibment are used for making paints, which after the coil-coating onto the substrate form the coatings. For the functionalization, the pigment is dispersed in a solution of an aminosilane in a solvent or a mixture of a solvent and a binder without an addition of a non-aminosilane dispersing agent with or without subsequent grinding and use of 0.05-30% of aminosilane on pigment. An aromatic, aliphatic, cycloaliphatic, ketone, ester, ether or alcohol compound or a mixture thereof can be used as the solvent. A silicone-polyester, polyurethane or fluoropolymer can be used as the binder.Type: ApplicationFiled: February 4, 2013Publication date: June 13, 2013Applicants: Helios, Tovarna Barv, Lakov In Umetnih, Alanod Aluminium-Veredlung GmbH & Co.

Patent number: 8455088Abstract: The present disclosure relates to compounds from which nanofibers can be produced, the resulting nanofibers produced from the compounds, and nanofiber reinforced polymers prepared using the nanofibers and a polymer. The compounds used in forming the nanofibers include chemical linkage moieties that are capable of forming non-covalent bonds with portions of the polymer so as to form the nanofiber reinforced polymers. The nanofiber reinforced polymers are useful as biomaterials in medical devices.Type: GrantFiled: December 23, 2005Date of Patent: June 4, 2013Assignee: Boston Scientific Scimed, Inc.Inventors: Scott R. Schewe, Michele L. Zoromski, Liliana L. Atanasoska, Robert W. Warner

Patent number: 8399542Abstract: Disclosed is a method for making a poly-lactic acid/silica composite. At first, silica particles are aminated, thus providing aminated silica particles. Secondly, the aminated silica particles are mixed with poly-lactic acid. Then, the mixture is blended and extruded by two micro-screws, thus providing a poly-lactic acid/silica composite. Thus, the mechanical properties of the poly-lactic acid are improved without affecting the biodegradability of the poly-lactic acid.Type: GrantFiled: July 29, 2011Date of Patent: March 19, 2013Assignee: Chung-Shan Institute of Science and Technology, Armaments, Bureau, Ministry of National DefenseInventors: Cheng-Chien Yang, Jui-Ming Yeh, Tsao-Cheng Huang
