Patent number: 6258454Abstract: Low surface energy functionalized surfaces on solid supports are provided by treating a solid support having hydrophilic moieties on its surface with a derivatizing composition containing a mixture of silanes. A first silane provides the desired reduction in surface energy, while the second silane enables functionalization with molecular moieties of interest, such as small molecules, initial monomers to be used in the solid phase synthesis of oligomers, or intact oligomers. Molecular moieties of interest may be attached through cleavable sites. Derivatizing compositions for carrying out the surface functionalization process are provided as well.Type: GrantFiled: September 1, 1998Date of Patent: July 10, 2001Assignee: Agilent Technologies Inc.Inventors: Steven M. Lefkowitz, Geraldine Fulcrand, Douglas J. Dellinger, Charles Z. Hotz

Method for manufacturing a chemically adsorbed film and a chemical adsorbent solution for the method
Publication number: 20010005531Abstract: The methods of forming a chemically adsorbed film by contacting a substrate with a solution mixture containing an alkoxysilane surface active agent, a non-aqueous solvent and a silanol-condensing catalyst to form a film covalently bonded to the substrate via siloxane bonds. These methods do not generate hydrochloric acid gas in forming the films and allow practical reaction rates.Type: ApplicationFiled: January 29, 2001Publication date: June 28, 2001Inventor: Kazufumi Ogawa -
Patent number: 6238745Abstract: A water repellent for treating solids provides an durable and robust water repellency. The active ingredient in the water repellent is a pendant carbosiloxane dendrimer-functional vinyl-type polymer. A spray-formulated water repellent for treating solids contains 0.5 to 20 weight % of the pendant carbosiloxane dendrimer-functional vinyl-type polymer, 30 to 98.5 weight % of an organic solvent, and 1 to 50 weight % of a propellant gas.Type: GrantFiled: November 23, 1999Date of Patent: May 29, 2001Assignee: Dow Corning Toray Silicone Co. Ltd.Inventors: Yoshitsugu Morita, Takayuki Aso, Haruhiko Furukawa

Patent number: 6235833Abstract: A water-repellent solution for forming a superior water-repellent film on a glass substrate is produced by subjecting a fluoroalkyl-group contained silane compound to a hydrolysis and a condensation polymerization. With this, at least dimers and trimers of the silane compound are produced. In case wherein the fluoroalkyl-group contained silane compound is of a type having the following general formula, satisfied performance of the formed water-repellent film is expected: CF3(CF2)m(CH2)2SiX3 wherein “m” is equal to or greater than 7 (seven) and “X” represents halogen, isocyanate-group or alkoxy-group, said alkoxy-group including methoxy-group [OCH3], ethoxy-group [OC2H5] or isopropoxy-group [OC3H5]. When the “m” is equal to or greater than 9 (nine), the performance of the film is much increased.Type: GrantFiled: February 12, 1999Date of Patent: May 22, 2001Assignee: Central Glass Company, LimitedInventors: Yoshinori Akamatsu, Shigeo Hamaguchi
