Abstract: Dimensionally-stable fibrous structures including ceramic-coated melt-blown nonwoven fibers made of a flame-retarding polymer and processes for producing such fire-resistant nonwoven fibrous structures. The melt-blown fibers include poly(phenylene sulfide) in an amount sufficient for the nonwoven fibrous structures to pass one or more fire-resistance test, e.g. UL 94 V0, FAR 25.853 (a), FAR 25.856 (a), and CA Title 19, without any halogenated flame-retardant additive, and have a ceramic coating. The melt-blown fibers are subjected to a controlled in-flight heat treatment at a temperature below a melting temperature of the poly(phenylene sulfide) immediately upon exiting from at least one orifice of a melt-blowing die, in order to impart dimensional stability to the fibers. The nonwoven fibrous structures including the in-flight heat-treated melt-blown fibers exhibit a Shrinkage less than a Shrinkage measured on a nonwoven fibrous structure including only fibers not subjected to the controlled in-flight heat treatment operation, generally less than 15%.

Abstract: Surface structured articles comprising a polymer matrix and a dispersed phase, the article having first and second opposed major surfaces, at least a portion of the first major surface is a microstructured, anisotropic surface comprises features having at least one dimension in a range from 1 micrometer to 500 micrometers, wherein the dispersed phase comprises an antimicrobial material, and wherein at least a portion of the dispersed phase is present on the microstructured, anisotropic surface. Surface structured articles are useful, for example, for marine applications (e.g., surfaces in contact with water (e.g., fresh water, ocean water)) such as boats, ships, piers, oil rigs, decks, and roofing materials.

Abstract: A method of making a nanostructure and nanostructured articles by depositing a layer to a major surface of a substrate by plasma chemical vapor deposition from a gaseous mixture while substantially simultaneously etching the surface with a reactive species. The method includes providing a substrate; mixing a first gaseous species capable of depositing a layer onto the substrate when formed into a plasma, with a second gaseous species capable of etching the substrate when formed into a plasma, thereby forming a gaseous mixture; forming the gaseous mixture into a plasma; and exposing a surface of the substrate to the plasma, wherein the surface is etched and a layer is deposited on at least a portion of the etched surface substantially simultaneously, thereby forming the nanostructure. The substrate can be a (co)polymeric material, an inorganic material, an alloy, a solid solution, or a combination thereof. The deposited layer can include the reaction product of plasma chemical vapor deposition using a reactant gas comprising a compound selected from the group consisting of organosilicon compounds, metal alkyl compounds, metal isopropoxide compounds, metal acetylacetonate compounds, metal halide compounds, and combinations thereof. Nanostructures of high aspect ratio and optionally with random dimensions in at least one dimension and preferably in three orthogonal dimensions can be prepared.
