Abstract:
Methods for the preparation of polymer-templated core-shell nanoparticles include the steps of (a) preparing a cationic polymeric core material comprising polymeric micelles, and (b) coating the core material with a silica-comprising shell by depositing the shell onto the polymeric micelles from at least one silica precursor to form the core-shell nanoparticles. Compositions which include the core-shell nanoparticles are adapted to facilitate controlled delivery of at least one active agent into a system in response to controlled changes in the pH of the system.
Abstract:
The invention is based on the recognition that known antimicrobial compounds, such as nisin or other lantibiotics, can be made to form a long lasting antimicrobial surface coating by linking the peptide with a block polymer, such as PLURONIC® F108 or an end group activated polymer (EGAP) in a manner to form a flexible tether and/or entrap the peptide. The entrapped peptide provides antimicrobial action by early release from entrapment while the tethered peptide provides longer lasting antimicrobial protection. Antimicrobial gels and foams may be prepared using the antimicrobial peptide containing block copolymers.

Abstract:
The invention relates to a flame retardant product comprising a one or two dimensional substrate further comprising a crystalline triazine layer. The amount of trazine is such that the flame retardant properties of the substrate are improved and preferably the amount is about 0.1 g/m2 or higher, and about 500 g/m2 or lower. The triazine is preferably vapor deposited, and is preferably melamine.

Abstract:
An ethylene-vinyl alcohol copolymer (EVOH) composition comprises 100 parts by weight of a powder (A) having a particle size of from 22 to 850 μm of an ethylene-vinyl alcohol copolymer (a) which has an ethylene content of from 2 to 60 mol % and has a degree of saponification greater than 95%, and from 0.0001 to 2 parts by weight of inorganic particles (B) having primary particles with a mean particle size of from 1 to 100 nm. The EVOH powder coating composition of the present invention forms a coating film having good uniformity when applied to a substrate as powder coating, even when it contains 1 part by weight or more water relative to 100 parts by weight of EVOH resin.
Abstract:
The invention relates to the use of microparticles hydrophobized with fluorosilanes or -siloxanes for producing surfaces which have self-cleaning and also lactophobic, oleophobic and lipophobic properties. The use of microparticles hydrophobized with fluorosilanes in the known processes for producing self-cleaning surfaces makes it possible to produce surfaces which have not only self-cleaning properties but also lipophobic, oleophobic and lactophobic properties. Articles finished with such surfaces are especially easy to clean easily with removal of oil-, grease- or milk-containing soilings. The inventive use is therefore especially suitable for producing industrial textiles, workwear and children's clothing.

Abstract:
Size-confined nanocomposite powders and methods for their manufacture are provided by coating fine powders with a nanoscale powder of a different composition. The nanocomposite plastics offer performance characteristics approaching those of metals and alloys. The nanocomposite powders are alternatively used for dispersion strengthening of metals, alloys, and ceramics. Materials based nanotechnology for energy devices and programmable drug delivery are included.
Abstract:
A resin for use in molding, sintering, or extruding finished parts, the resin comprising a plurality of polymeric particles and a coating of at least one additive covering each of the polymeric particles. The method of preparing the resin comprises the steps of combining at least one additive, a plurality of polymeric particles, and at least one liquid to form a suspension; and removing at least a portion of the liquid from the suspension to thereby form at least a partial additive coating on each polymeric particle.
Abstract:
A granular resin solid (a) that serves as a nucleus, has a particle size of 0.5 to 7 mm, and is composed of a molding thermoplastic resin, a powdered additive component (b), and a fixing resin (c) composed of a thermoplastic resin are stirred and mixed, the fixing resin (c) is melted by the frictional heat during stirring and mixing, the powdered additive component (b) is made to adhere to the surface of the granular resin solid (a) by the melted fixing resin (c), and the system is cooled while being stirred, which solidifies the fixing resin (c), thereby providing a granular additive with excellent dispersibility and a uniform particle size by an extremely simple method and at low cost. It is also possible to dissolve the fixing resin (c) in a solvent to obtain a liquid adhesive agent (d), which is then stirred and mixed into the granular resin solid (a) and the powdered additive component (b), causing the powdered additive component (b) to adhere to the surface of the granular resin solid (a), and evaporate the solvent of the liquid adhesive agent (d) by further stirring and solidify the fixing resin (c), thereby affixing the additive component (b) to the surface of the granular resin solid (a).
