    Abstract: The present disclosure provides polyimide fibers with kidney-shaped cross-section and their preparation methods thereof, falling within the technical field of polyimide fiber. Polyimide fibers with kidney-shaped cross-sections are prepared by a continuous, integrated approach, starting from a polyamic acid solution prepared by reacting an aromatic dianhydride with an aromatic diamine. PAA nascent fibers with kidney-shaped cross-sections are obtained by adopting a spinneret having circular orifices under wet spinning process. The kidney-shaped cross-sections are obtained by varying the processing condition, including spinning speed, coagulation bath composition, coagulation temperature, and depth of coagulation bath. After washing and drying, polyamic acid nascent fibers are converted to polyimide fibers with kidney-shaped cross-sections under thermal curing. The integrated preparation methods are suitable for mass industrial production.

    Abstract: One embodiment of a method for producing a plurality of nanostructures embedded in a host comprising the steps of: assembling a first preform, drawing said first preform into a first fiber, cutting said first fiber into a plurality of pieces, assembling said pieces of said first fiber into a second preform, and drawing said second preform into a second fiber. The host is made of a low thermal conductivity material such as a polymer or combination of polymers. The host can assume the form of a plurality of nanotubes which further reduces the host's thermal conductivity due to enhanced phonon scattering. The host can exhibit anisotropic thermal conductivity which reduces its thermal conductivity perpendicular to the direction in which it was drawn. The nanostructure-host composite can be cut into pieces and assembled into efficient thermoelectric devices for use in cooling or electric power generation applications. Other embodiments are described and shown.

  • Patent number: 8765040
    Abstract: Methods of fabricating a polymeric implantable device, such as a stent, with improved fracture toughness through annealing a polymer construct below the glass transition temperature of the polymer of the construct prior to a deformation step are disclosed herein. The deformation of the construct induces crystallization in the polymer construct through strain-induced crystallization. The annealing of the polymer construct accelerates the crystallization induced during the deformation and results in an increase in crystallite density with smaller crystallites as compared to deformation of a tube that has not been annealed. A stent scaffolding is then made from the deformed tube.

  • Patent number: 8691132
    Abstract: Stretch film is treated by passing a web of tackifier-containing, unbloomed thin polymer film through a heater so that the web is heated to a temperature sufficient to cause tackifier bloom prior to the web reaching a next stage in an in-line process. Also, a pattern can be applied to a thin polymer film. An oriented web of thin polymer film is passed across at least one heated roller having the pattern engraved thereon to define face regions and relief regions collectively conforming to the pattern. As the web contacts each roller surface, portions of the web positioned over the relief regions receive less heat than portions of the web positioned over the face regions, thereby causing the respective portions of the web to undergo differential, heat-induced shrinkage which imparts the pattern to the thin polymer film.

  • Patent number: 8685305
    Abstract: The invention aims at providing a heat-shrinkable polyester film which is excellent in tearability along perforations and in break resistance after storage when used as labels of beverage bottles. The invention relates to a heat-shrinkable polyester film which is made of a polyester resin comprising ethylene terephthalate as the main constituent and containing at least 13 mol % of at least one monomer capable of forming an amorphous component in the whole polyester resin component and which has specific heat shrinkage characteristics and exhibits specific mechanical characteristics after heat shrinking treatment. The film can be produced by a sequential biaxial orientation process comprising longitudinal orientation step, intermediate heat treatment step, positive cooling step, transverse orientation step, and final heat treatment step.

  • Patent number: 8632653
    Abstract: A method of manufacturing curved composite structural elements can include fabricating a web ply in a flat curve over a removable substrate and laying up the ply on a curved web surface of a manufacturing tool. The method also can include laying up a diagonal ply with fibers oriented at +/?45° from the centerline of the web surface. The method further can include cutting a unidirectional composite tape into segments and laying up the tape segments to form a cross ply with a fiber orientation normal to the centerline of the web surface. One or both edges of the diagonal and cross plies may be folded over one or two sides of the manufacturing tool to form one or two flange surfaces. Additionally, a cap ply can be laid up on one or both flange surfaces using composite tape. The structural element layup can then be inspected and any excess composite material can be trimmed away.
