Publication number: 20090026122Abstract: A biocompatible coating for solid phase microextraction (SPME) of a small molecule from a biological matrix. The coating comprises SPME particles and a biocompatible polymer. The biocompatible polymer (e.g. polyacrylonitrile) reduces adsorption of proteins or macromolecules onto the SPME particles and allows the SPME particles to extract the small molecule from the matrix. A process for coating a flexible fiber with a biocompatible coating. The process comprises: coating the fiber with a suspension of SPME particles, the SPME particles being suspended in a solution of a biocompatible polymer and a solvent, the biocompatible polymer can comprise polyacrylonitrile (PAN); drying the coated fiber to remove the solvent; and curing the dried coated fiber at an elevated temperature.Type: ApplicationFiled: July 16, 2008Publication date: January 29, 2009Applicant: JanuszInventors: Janusz B.

Publication number: 20090018249Abstract: A hydrophobic self cleaning coating composition that can be applied by conventional methods such as by spraying the composition onto a surface forming creating a wet and dry dirt repellent coating on the surface. The coating utilizes hydrophobic nanoparticles of fumed silica and/or titania in a solvent which evaporates at ambient temperature. The coating solves the problem of poor resistance to UV light, opaque appearance, and/or abrasion found in previous coatings of similar nature. Virtually transparent coating are produced as compared to conventional coatings of comparable hydrophobicity which are typically white or opaque. The coating can be applied by a single and easy spraying method and the super hydrophobic property can be achieved by drying the film by evaporation of the solvent at ambient temperature for 5 to 10 minutes.Type: ApplicationFiled: January 30, 2007Publication date: January 15, 2009Inventors: Subbareddy Kanagasabapathy, Richard J.

Patent number: 7476707Abstract: A high solid polyester polyol/silica nanocomposite resin with low viscosity is synthesized by an in situ polymerization method, namely conducting condensation polymerization of polyol/diacid monomer with a molar ratio of 1.1˜1.5 in the presence of colloidal silica nanoparticles with a diameter of 10˜150 nm. The resulted nanocomposite resins has a solid content of >95%, molecular weight of 1000˜5000 g/mol and hydroxyl value of 80-200 mg KOH/g, and a viscosity in the range of 800-2000 mPa.s. The viscosities are especially lower than those obtained by a blending method. The nanosilica content in the nanocomposite resin is 1˜15% (based on the total solid content of nanocomposite resin). The high solid polyester polyol/silica nanocomposite resin was curable with isocyanate or melamine to prepare high solid transparent nanocomposite coatings with obviously improved abrasion and scratch resistance, hardness, weatherability etc.Type: GrantFiled: January 18, 2005Date of Patent: January 13, 2009Assignee: Fudan UniversityInventors: Limin Wu, Shuxue Zhou, Yongchun Chen, Bo You, Guangxin Gu
