Disclosed are systems and methods for the formation of a polymer nanocomposite material using a high-concentration masterbatch as a source of nanocomposite filler.

Nanocomposite method of manufacture

Disclosed is a novel polymeric composite including a nanoparticle filler and method for the production thereof. More particularly, the present invention provides a novel halloysite nanoparticle filler which has the generally cylindrical or tubular (e.g. rolled scroll-like shape), in which the mean outer diameter of the filler particle is typically less than about 500 nm. The filler is effectively employed in a polymer composite in which the advantages of the tubular nanoparticle filler are provided (e.g., reinforcement, flame retardant, chemical agent elution, etc.) with improved or equivalent mechanical performance of the composite (e.g., strength and ductility).

Polymeric composite including nanoparticle filler

The present invention relates to a method for making an open celled microcellular foam comprising providing at least one foamable polymer and a crosslinking agent in an extruder, injecting at least one blowing agent into said at least one foamable polymer and said crosslinking agent in said extruder, blending said blowing agent injected into said at least one foamable polymer and said crosslinking agent in said extruder, feeding said blended blowing agent, at least one foamable polymer and said crosslinking agent in said extruder to a die, and depressurizing said blended blowing agent, said at least one foamable polymer and said crosslinking agent.

Manufacturing process for open celled microcellular foam

Disclosed is an optical element comprising in order a light source, air, at least one thin layer having a thickness of 80 to 200 nm, and a thick layer, each layer varying in refractive index (RI) by at least 0.05 from the next adjacent layer, in an alternating manner.

Optical element containing an interference fringe filter

This invention relates to an imaging element comprising a base polyester layer, an absorbent polyester layer above said base layer, and a glossy polymer layer above said absorbent layer; wherein said element has a 60&deg; Gardner gloss greater than 30% wherein said glossy polymer layer has openings comprising between 5.0 and 10.0% of the surface area

Gloss coating on permeable surface imaging support

A photographic polyester support having an adjacent subbing layer which comprises a polymer or copolymer of glycidyl acrylate and/or glycidyl methacrylate followed by a gelatin layer and which is annealed. Such a composite has been found to provide improved adhesion properties without chemical degradation of the subbing layer under annealing conditions.

Annealed adhesion promoting layer for photographic imaging elements

A polyester support having an adjacent subbing layer which comprises a polymer or copolymer of glycidyl acrylate and/or glycidyl methacrylate improves the adhesion of a photothermographic imaging layer containing a poly(vinyl butyral) binder coated from an organic solvent. The subbing layer can be applied in the form of an aqueous dispersion in the prescence of a coalescing agent. Such a subbing layer does not adversely affect sensitometry in a photothermographic or thermographic element.

Imaging elements adhesion promoting subbing layer for photothermographic

A composite support for an imaging element is described, which composite support comprises a polymeric film and an electrically conductive layer, wherein the polymeric film comprises a surface which has been activated by energetic treatment, the electrically conductive layer comprises an electrically conductive agent dispersed in an aqueous dispersible polymeric binder comprising an aliphatic, anionic polyurethane having an ultimate elongation to break of at least 350 percent, and the electrically conductive layer is in contiguous contact with the activated surface of the polymeric film. Imaging elements for use in an image-forming process are also described, which element comprise such composite supports and at least one image-forming layer. The invention provides composite supports and imaging elements containing an electrically conductive antistatic layer having excellent adhesion to energetic surface-treated polymer film supports, and of auxiliary layers to the electrically conductive antistatic layer.
