Abstract:

This invention is a process for making modified silica filler comprising the steps of: (A) contacting an acidic aqueous suspension of precipitated or colloidal silica, optionally in the presence of a surfactant and/or a water-miscible solvent, with a combination of (a) a functionalizing coupling agent, and (b) an organometallic hydrophobing compound in a weight ratio of (a) to (b) of at least 0. 001 to 1 to form an acidic aqueous suspension of chemically treated silica filler having a pH of 2. 0 or less (B) treating the acidic aqueous suspension of the chemically treated filler with an acid-neutralizing agent to increase the pH of the suspension to a range of from greater than 2. 0 to 10, and (C) recovering the chemically treated filler. This invention is also modified silica filler that has a pH of from about 5. 0 to 10. 0, where the silica filler is made by the method of this invention.

Abstract:

Conductive curable compositions contain a free radical polymerizable monomer, oligomer or polymer (i); an organoborane amine complex (ii), and an electrically or thermally conductive filler (iii). The conductive curable compositions can also contain an amine reactive compound having amine reactive groups (iv); and (v) a component capable of generating a gas when mixed with a compound bearing active hydrogen and a catalyst. The electrically conductive curable compositions can be used in composite articles of manufacture in which substrates are coated or bonded together with the composition and cured; and as electrically conductive rubbers, electrically conductive tapes, electrically conductive adhesives, electrically conductive foams, and electrically conductive pressure sensitive adhesives. The thermally conductive compositions can also be used in composite articles of manufacture in which substrates are coated or bonded together with the composition and cured, and as thermal interface materials, thermally conductive rubbers, thermally conductive tapes, thermally conductive adhesives, thermally conductive foams, thermally conductive seals and gaskets, and thermally conductive pressure sensitive adhesives.

Abstract:

A free standing film includes: i. a matrix layer having opposing surfaces, and ii. an array of nanorods, where the nanorods are oriented to pass through the matrix layer and protrude an average distance of at least 1 micrometer through one or both surfaces of the matrix layer. A method for preparing the free standing film includes (a) providing an array of nanorods on a substrate, optionally (b) infiltrating the array with a sacrificial layer, (c) infiltrating the array with a matrix layer, thereby producing an infiltrated array, optionally (d) removing the sacrificial layer without removing the matrix layer, when step (b) is present, and (e) removing the infiltrated array from the substrate to form the free standing film. The free standing film is useful as an optical filter, ACF, or TIM, depending on the type and density of nanorods selected.
