Abstract: New photoresist compositions are provided that comprise a component that comprises an amide group and multiple hydroxyl groups. Preferred photoresists of the invention may comprise a resin with photoacid-labile groups; a photoacid generator compound; and an amide component with multiple hydroxyl groups that can function to decrease undesired photogenerated-acid diffusion out of unexposed regions of a photoresist coating layer.

Abstract: The present invention provides a process for the production of functionalized carbon nanotubes. The inventive process for the production of functionalized carbon nanotubes involves reacting carboxylic acid moieties of oxidized carbon nanotubes with vapors of a compound containing carboxylic acid reactive groups to produce functionalized carbon nanotubes. The present invention also provides a composition made from a plastic resin and functionalized carbon nanotubes produced by reacting carboxylic acid moieties of oxidized carbon nanotubes with a vapor containing carboxylic acid reactive groups to produce functionalized carbon nanotubes. The inventive process is useful with single-walled carbon nanotubes, double-walled carbon nanotubes and multi-walled carbon nanotubes.
Abstract: A composite barrier membrane coated on a substrate and membrane is formed by phase inversion technique utilizing a water-insoluble wax and a water-insoluble polymer dissolved in a solvent. The barrier membrane coated upon the substrate is used to control transmembrane transport of a liquid and a gas. The substrate can be a starch based food package material, a protein based food package materials, a natural fabric, a synthetic fabric, or a paper product.
