Publication number: 20160222208Abstract: The present invention relates to a thermoplastic resin composition and a molded article manufactured using the thermoplastic resin composition. Particularly, the thermoplastic resin composition may be reinforced with the carbon fiber. Accordingly, the thermoplastic resin composition may be obtained by mixing a carbon fiber, a silane-based coupling agent and a thermoplastic elastomer to a polyamide-6 polymer having low specific gravity, such that weight thereof may be reduced and economical efficiency may be improved. Further, parts assembly efficiency and stability of the injection molded product from the thermoplastic resin composition of the present invention may be improved by minimizing deformation after injection molding due to improved rigidity, durability and dimensional stability thereof. The thermoplastic resin composition may be used for parts of vehicle exterior material such as a panorama sunroof frame.Type: ApplicationFiled: December 14, 2015Publication date: August 4, 2016Inventors: Sang Sun Park, Kyung Min Yu, Kie Youn Jeong, Seok Hwan Kim, Hyung Tak Lee, Woong Jae Boo, Jong Tae Seo

Publication number: 20120136093Abstract: A two step method for preparing a filler composition, the filler composition useful to prepare a nanocomposite polymer and an epoxy nanocomposite coating. First, disperse a water dispersible filler material in a liquid comprising water, but without any added intercalation agent, to form a dispersion. Second, replace at least a portion of the water of the liquid with an organic solvent so that the water concentration of the liquid is less than six percent by weight to form the filler composition, the average size of at least one dimension of the filler material being less than two hundred nanometers upon examination by transmission electron microscopy of a representative freeze dried sample of the dispersion of the first step. A nanocomposite polymer can be prepared by mixing the filler composition with one or more polymer, polymer component, monomer or prepolymer to produce a polymer containing the filler composition.Type: ApplicationFiled: January 16, 2012Publication date: May 31, 2012Applicants: THE TEXAS A & M UNIVERSITY, DOW GLOBAL TECHNOLOGIES LLCInventors: Luyi Sun, Woong Jae Boo, Hung-Jue Sue, Maurice J.
