Publication number: 20140023862Abstract: A process of making an agglomerated particle cloud network coated fiber bundle containing forming a bundle of fibers, coating the bundle of fibers with a nanoparticle solution, and drying the solvent from the coated bundle of fibers at a temperature above room temperature forming an agglomerated particle cloud network coated fiber bundle comprising a plurality of agglomerated nanoparticles. The agglomerated nanoparticles are located in at least a portion of the void space in the bundle of fibers and form bridges between at least a portion of the adjacent fibers. Between about 10 and 100% by number of fibers contain bridges to one or more adjacent fibers within the agglomerated particle cloud network coated fiber bundle. The agglomerated nanoparticles form between about 1 and 60% of the effective cross-sectional area of the agglomerated particle cloud network coated fiber bundle.Type: ApplicationFiled: July 23, 2012Publication date: January 23, 2014Inventors: Ryan W.

Publication number: 20140004358Abstract: Low k dielectric films/layers can be produced by cross-linking oligomers made from cyclic carbosilane monomers. The films may exhibit high porosity and strong resistance to chemical attack while also exhibiting improved hydrophobicity. Oligomers may be cross-linked in situ after coating on a substrate such as a silicon wafer. Resulting cross-linked layers may be further treated to improve chemical resistance and reduce water uptake.Type: ApplicationFiled: June 28, 2012Publication date: January 2, 2014Inventors: James M. Blackwell, David J. Michalak

Patent number: 8592072Abstract: A battery separator (13) of the present invention includes a porous film (12) serving as a substrate and a crosslinked polymer layer (11) supported on the porous film (12). The crosslinked polymer layer (11) contains a crosslinked polymer and inorganic particles, and is non-porous. The crosslinked polymer is obtained by reacting a reactive polymer having a functional group in its molecule with a polyfunctional compound reactive with the functional group so as to crosslink at least a part of the reactive polymer. A lithium ion secondary battery of the present invention includes a positive electrode (14), a negative electrode (15), the battery separator (13) of the present invention disposed between the positive electrode (14) and the negative electrode (15), and a non-aqueous electrolyte solution. The battery separator (13) is disposed so that the porous film (12) faces the negative electrode (15) and the crosslinked polymer layer (11) faces the positive electrode (14).Type: GrantFiled: September 7, 2009Date of Patent: November 26, 2013Assignee: Nitto Denko CorporationInventors: Hiroyoshi Take, Shunsuke Noumi, Chiharu Odane, Takuji Shintani
