    Abstract: An RF inductor such as a Tesla antenna splices nanotube ends together to form a nanostructure in a polymer foam matrix. High Internal Phase Emulsion (HIPE) is gently sheared and stretched in a reactor comprising opposed coaxial counter-rotating impellers, which parallel-align polymer chains and also carbon nanotubes mixed with the oil phase. Stretching and forced convection prevent the auto-acceleration effect. Batch and continuous processes are disclosed. In the batch process, a fractal radial array of coherent vortices in the HIPE is preserved when the HIPE polymerizes, and helical nanostructures around these vortices are spliced by microhammering into longer helices. A disk radial filter produced by the batch process has improved radial flux from edge to center due to its area-preserving radial vascular network. In the continuous process, strips of HIPE are pulled from the periphery of the reactor continuously and post-treated by an RF inductor to produce cured conductive foam.

  • Patent number: 8247464
    Abstract: A selective high intensity ultrasonic foaming technique is described to fabricate porous polymers for biomedical applications. Process variables, including ultrasound power, scanning speed, and gas concentration have an affect on pore size. Pore size can be controlled with the scanning speed of the ultrasound insonation and interconnected porous structures could be obtained using a partially saturated polymers. A gas concentration range of 3-5% by weight creates interconnected open-celled porous structures. The selective high intensity ultrasonic foaming method can be used on biocompatible polymers so as not to introduce any organic solvents. The method has use in cell related biomedical applications such as studying cell growth behaviors by providing a porous environment with varying topological features.

  • Patent number: 8227521
    Abstract: Fluoropolymer foams are prepared by mixing fluoropolymer resin with blowing agents and additives to produce foamable compounds at temperatures below the activation temperature of the blowing agent. The compounded material is expanded at temperatures above both the softening point of the fluoropolymer resin and the activation temperature of the blowing agent. The resulting fluoropolymer foam can be fabricated into any desired shape, such as pipes, sheets, tapes, blocks and rods, using techniques such as cutting, welding, thermoforming and adhesive bonding. Alternatively the fluoropolymer compound may be expanded directly into the desired shape, for example, by expanding the compound in a mold.

  • Publication number: 20120087859
    Abstract: The present invention relates to a biopolymer-modified nanocarrier in which chitosan is bound to a water-soluble biocompatible polymer that has been crosslinked via a photo-crosslinkable functional group; wherein the chitosan-modified nanocarrier has a diameter which changes in accordance with changes in temperature, has enhanced skin permeability or cellular uptake and selective delivery to cancer tissue as compared with a bare nanocarrier to which chitosan has not been bound, and exhibits characteristics that are advantageous in photothermal therapy. The chitosan-modified nanocarrier of the present invention exhibits highly superior efficacy as a transdermal carrier, since the skin permeability is enhanced to a significant level as compared with a bare nanocarrier that has no chitosan.

  • Publication number: 20110275727
    Abstract: Disclosed is a resin foam which excels in properties such as strength, flexibility, cushioning properties, and strain recovery, particularly has a cell structure resistant to shrinkage caused by the restoring force of the resin, and has a high expansion ratio. The cross-linked resin foam is obtained by heating a resin composition containing an elastomer, an active-energy-ray-curable compound, and a thermal crosslinking agent to form a cross-linked structure derived from the thermal crosslinking agent in the resin composition; subjecting the cross-linked-structure-containing resin composition to foam molding to give a foamed structure; and irradiating the foamed structure with an active energy ray to form another cross-linked structure derived from the active-energy-ray-curable compound to give the cross-linked resin foam.

  • Publication number: 20110256628
    Abstract: The embodiments described herein include porous scaffolds formed from a stimuli-responsive polymer. The stimuli-responsive polymer of the scaffold creates a “smart” scaffold that changes properties in response to an effective stimulus applied to the stimuli-responsive polymer. In a preferred embodiment, an effective stimulus applied to the scaffold initiates a phase transition event in the stimuli-responsive polymer that results in a change in the volume of the pores of the scaffold. The scaffolds can be used to capture appropriately sized objects (e.g., cells) by using the volume-change properties of the pores. Relatedly, the scaffolds can be used as tissue-engineering scaffolds by capturing cells in the pores and introducing the cell-loaded scaffold into a cell-growth environment (e.g., in vivo).
