专利号:US-2019016909-A1 优先权日:2016-01-11 标题:Template synthesis of polymeric nanomaterials by ink-jet printing 发明人:PHILLIP WILLIAM A; QU SIYI; BENAVIDES SHERWOOD; GAO PENG; GAO FENG 权利人:UNIV NOTRE DAME DU LAC 摘要:A method for fabricating nanostructured polymeric materials based on a combination of inkjet printing and template synthesis. Layer-by-layer assembled nanotubes can be synthesized in a polycarbonate track-etched (PCTE) membrane by printing poly(allylamine hydrochloride) (PAH) and poly(styrenesulfonate) (PSS) sequentially. By changing the printing conditions, polymeric nanotubes or nanowires can be prepared by printing poly(vinyl alcohol) (PVA) in a PCTE template. Inkjet printing paired with template synthesis can be used to generate patterns comprised of chemically distinct nanomaterials. Thin polymeric films of layer-by-layer assembled PAH and PSS can be printed on a PCTE membrane. Inkjet printing paired with template synthesis can also be used to prepare functional mosaic membranes, such as charge mosaic membranes comprising polyelectrolytes of different charges to pattern positively charged or negatively-charged domains, respectively, on the surface of the template.

专利号:US-6103865-A 优先权日:1998-08-03 标 题 :PH-sensitive polymer containing sulfonamide and its synthesis method 发明人:BAE YOU HAN; PARK SANG YEOB 权利人:KWANGJU INST SCI & TECH 摘要:There are disclosed pH-sensitive polymers containing sulfonamide groups, which can be changed in physical properties, such as swellability and solubility, depending on pH and which can be applied for a drug-delivery system, bio-material, sensor, etc, and a preparation method therefor. The pH-sensitive polymers are prepared by introduction of sulfonamide groups, various in pKa, to hydrophilic groups of polymers either through coupling to the hydrophilic groups, such as acrylamide, N,N-dimethylacrylamide, acrylic acid, N-isopropylacrylamide, etc, of polymers or copolymerization with other polymerizable monomers. These pH-sensitive polymers may have a structure of linear polymer, grafted copolymer, hydrogel or interpenetrating network polymer.
