Abstract: A thermoplastic resin composition comprises: about 100 parts by weight of a polycarbonate resin; about 3 parts by weight to about 20 parts by weight of a rubber-modified aromatic vinyl copolymer resin; about 12 parts by weight to about 28 parts by weight of talc having an average particle size of about 8 ?m to about 20 ?m and a blackness degree L* of less than about 90; about 5 parts by weight to about 20 parts by weight of acicular inorganic fillers; and about 10 parts by weight to about 30 parts by weight of a phosphorus flame retardant. The thermoplastic resin composition can have good properties in terms of light shielding, impact resistance, dimensional stability, flame retardancy, balance therebetween, and the like.

Abstract: A composite ultra-thin coating film with hypersensitivity inflammatory reaction inhibition and antibacterial activity, an implant comprising the same, and a method for preparing the same are described. The composite ultra-thin coating film can be applied to medical silicone-based polymers and exhibits excellent antibacterial activity and inhibits deformed cell proliferation so that hypertrophic tissue is not formed and there is no cytotoxicity.

Abstract: A method for preparing a nanoporous membrane includes alternatively repeating, on the surface of a porous substrate, the laminating of a hydrophilic homopolymer and the laminating of an amphiphilic block or graft copolymer to provide a polymer multilayer film in which the alternative laminate of the hydrophilic homopolymer and the amphiphilic block or graft copolymer is formed. The polymer multilayer film is annealed to form a microphase separated polymeric membrane. The laminating of a hydrophilic homopolymer and the laminating of a supramolecular structure compound are alternatively repeated, on the surface of the polymeric membrane, to form the alternative laminate of the hydrophilic homopolymer and the supramolecular structure compound.

Abstract: A knitting process include steps of (a) arranging first needles and second needles horizontally; (b) arranging third needles vertically; (c) moving the first needles rearward to form terries by picking up a thread; (d) moving the first needles forward and laterally to cause the first needles to clear the thread; (e) repeating steps (c) and (d) until a terry pattern is formed on a first surface of a fabric; (f) moving the first needle rearward to form terries by picking up the thread; (g) moving the first needle forward and laterally to cause the first needles to clear the thread; (h) moving the third needles upward and downward; (i) moving the second needles to pick up the thread; and (j) repeating steps (f) to (i) until a jacquard pattern is formed on a second surface of the fabric. This is a continuous process.

Abstract: A textile is provided with an underlying layer of hook and loop fabric; and a jacquard surface layer formed integrally with the underlying layer of hook and loop fabric. No adhesive is used in the manufacturing processes so as to minimize impact to the environment. The textile is particularly for the manufacturing of shoes and head covering.

Abstract: Forming graft copolymers in water using labeling of water soluble polymers with photoinitiators. Water soluble polymers can form environmentally responsive hydrophobically stimulated cages. The cages, which contain initiating radicals after irradiation, may be “opened” or “closed” by changes in environmental conditions. When the cage is closed, the radicals are trapped inside and thus do not cause substantial polymerization of water soluble monomers in the same solution. When the cage is closed, the radicals escape and cause polymerization. In another variation, hydrogels and graft copolymers are formed by covalently linking phototoinitiator groups to water soluble polymers that do not form cages. Thus, monomers may form grafts to the polymer, allowing formation of physical hydrogels.

Abstract: Forming graft copolymers in water using labeling of water soluble polymers with photoinitiators. The water soluble polymers can form environmentally responsive hydrophobically stimulated cages, which respond to pH, salt concentration, and/or the addition of water miscible solvents to the aqueous solutions. When the cage is “closed,” irradiation leads to radicals that cannot escape from the cage and therefore don't cause substantial polymerization of water soluble monomers in the same solution. When the cage is open via change of pH, salt concentration and/or solvent composition, the photochemically produced free radicals become exposed and cause polymerization. Under certain conditions, only graft copolymers will be formed. These graft copolymers can form a physical hydrogel in which the crosslinks are reversible. Consequently, the gel and sol states are likewise reversible.
