  • Publication number: 20120041221
    Abstract: A fibrillar, nanotextured coating is deposited on a substrate by contacting the substrate with a reaction mixture comprising a reagent which is hydrolyzable to produced a cross-linked reaction product, and a first solvent which solvates the reagent and the reaction product. The reagent is hydrolyzed so as to provide a cross-linked reaction product which is bonded to the substrate. The substrate is then contacted with a second solvent which is a non-solvent for the reaction product so as to cause nanoscopic phase separation of the reaction product, resulting in the formation of a fibrillar nanotextured coating which is bonded to the substrate. The thus produced coating may be subjected to further chemical modification. The method may be utilized to produce superhydrophobic coatings. Also disclosed are coatings made by the method of the present invention.

  • Patent number: 5990335
    Abstract: A di-p-tolyldialkylsilane derivative, a photoluminescence polymer formed from the derivative, and methods for preparing the derivative and polymer are provided. The di-p-tolyldialkylsilane derivative is represented by the following formula (1): ##STR1## where R.sub.1 and R.sub.2 are independently selected from the group consisting of phenyl and --(CH.dbd.CH).sub.k R.sub.3 (k is an integer between and inclusive of 0 and 2, and R.sub.3 is hydrogen or alkyl), and X.sup.2 is selected from the group consisting of hydrogen, halogen atom and cyano group. The di-p-tolylalkylsilane derivative of the formula (1) is very useful as a monomer of a functional polymer. The photoluminescence polymer formed from the di-p-tolylalkylsilane derivative of the chemical formula (1) contains a repeating unit having a silicon between the conjugated double bonds, thereby suppressing electron movement of the conjugated double bond. As a result, a range of colors between blue and green, particularly, blue, can be obtained.

  • Patent number: 5858599
    Abstract: An anti-offsetting oil including an organopolysiloxane having the formula (1) below and containing low molecular weight organopolysiloxanes having a molecular weight of 3,000 or less in a content of 50 ppm or less. ##STR1## wherein R.sub.f 's represent a perfluoroalkyl which may contain at least one ether linkage; R's represent a monovalent hydrocarbon group; Y's represent a divalent organic group having 2 to 5 carbon atoms; a represents an integer of 1 or more and b represents an integer of 0 or more, provided that a and b satisfy 3a+3b+2=15 to 4,000; and c and d are an integer of 0 to 3. This fluid has a good wettability to silicone rubber or fluorine forming the surfaces of fixing rolls of electrophotographic copying machines, and hence can effectively prevent offset. Since it contains no low-molecular weight organopolysiloxanes, the electric-contact failure may hardly occur.

  • Patent number: 5639845
    Abstract: A novel and very efficient method is disclosed for the introduction of perfluoroalkyl groups into an organopolysiloxane by utilizing the hydrosilation reaction with an organohydrogenpolysiloxane. Different from the conventional but inefficient hydrosilation reaction using a perfluoroalkyl-substituted ethylene as the olefin compound, the inventive method utilizes a propene-1 3-substituted by a perfluoroalkyl group compound as the olefin compound to react with an organohydrogenpolysiloxane by which a very high efficiency in the hydrosilation reaction can be obtained without side reactions which otherwise greatly decrease the yield of the desired perfluoroalkyl-containing organopolysiloxane product.

  • Patent number: 5545255
    Abstract: An ultra thin, water and oil repelling and durable overcoat is easily formed on a substrate surface via covalent bonding by applying a finishing agent of the invention, comprising a chemically adsorptive compound with a chlorosilyl group and a nonaqueous viscous liquid or solid medium, on the substrate surface. A finishing agent, comprising a chemically adsorptive compound with a chlorosilyl group and a nonaqueous viscous liquid or solid medium, is applied on a substrate surface comprising hydrophilic groups. The substrate surface is then reacted with the chemically adsorptive compound at room temperature, and the agent containing unreacted chemically adsorptive compound is removed. The generation of hydrochloric acid gas can be prevented by adding tertiary amine or amide in the molar amount of one to three times more than the chemically adsorptive compound contained in the finishing agent.
