    Abstract: A technique for forming fibers (e.g., nanofibers, microfibers, etc.) from an aqueous spinning solution is provided. Through careful control over the nature and relative concentration of the components in the solution, fibers can be formed that remain relatively water resistant. To help accomplish these unique features, a pH-sensitive polymer is employed in the spinning solution that is generally soluble in water at a certain pH value, yet generally insoluble in water at a different pH value. This property allows for selective adjustment of the pH both before and after spinning to control the water-solubility of the polymer as desired.

  • Publication number: 20140147616
    Abstract: The invention relates to a regenerated cellulose fiber (1?) the cross-section of which comprises an oblong, essentially flat section (3). The fiber according to the invention is characterized in that at least one limb (4, 5, 6, 7) branches off from the oblong section, wherein the length of said limb is at most 40% of the length of the oblong section (3).

  • Publication number: 20140138863
    Abstract: A method of preparing particles comprises forming by optical lithography a topographic template layer disposed on a surface of a substrate, which is suitable for spin casting. The template layer comprises a non-crosslinked template polymer having a pattern of independent wells therein for molding independent particles. Spin casting a particle-forming composition onto the template layer forms a composite layer comprising the template polymer and the particles disposed in the wells. The composite layer is removed from the substrate using a stripping agent that dissolves the template polymer without dissolving the particles. The particles are then isolated.

  • Publication number: 20140100351
    Abstract: Fibers can be formed from monomers derived from a biorenewable source. In an embodiment, a fiber forming composition that includes a monomer or mixture of monomers with at least one monomer being derived from a biorenewable source in placed in a fiber producing device. At least a portion of the fiber forming composition is ejected through an opening of the fiber forming device. The ejected fiber forming composition is subjected to light at wavelengths sufficient to activate a reaction which causes solidification of the fiber as the fibers are ejected from the fiber producing device.

  • Publication number: 20140087169
    Abstract: An apparatus for forming particles from a liquid, including a rotor assembly having at least one surface sized and shaped so as to define at least one capillary. Each capillary has an inner region adjacent an axis of rotation of the rotor assembly, an outer region distal from the axis of rotation, and an edge adjacent the outer region. The rotor assembly is configured to be rotated at an angular velocity selected such that when the liquid is received in the inner region of the at least one capillary, the liquid will move from the inner region to the outer region, adopt an unsaturated condition on the at least one surface such that the liquid flows as a film along the at least one surface and does not continuously span the capillary, and, upon reaching the edge, separates from the at least one surface to form at least one particle.

  • Publication number: 20140080993
    Abstract: The invention relates to polymeric fibers and a process of preparing polymeric fibers. The process comprises the steps of synthesizing a composite of thermotropic liquid crystalline polymer (TLCP) comprising multi-walled carbon nanotubes (MWNTs), and spinning the composite to form composite fibers. Specifically, the MWNTs are incorporated at a very low concentration. It is demonstrated that the as-spun TLCP/MWNTs composite fibers demonstrated significantly enhanced mechanical properties as compared with the control TLCP fibers without MWNTs. Fibers having 0.3 wt % MWNTs (C-3) demonstrated an increase of tensile modulus and strength by 38% and 32%, respectively, when compared with the control TLCP fiber without MWNTs.
