Publication number: 20120040185Abstract: Polylactic acid fibers formed from a thermoplastic composition that contains polylactic acid and a polymeric toughening additive are provided. The present inventors have discovered that the specific nature of the components and process by which they are blended may be carefully controlled to achieve a composition having desirable morphological features. More particularly, the toughening additive can be dispersed as discrete physical domains within a continuous phase of the polylactic acid.

Publication number: 20120040582Abstract: A method for forming biodegradable fibers is provided. The method includes blending polylactic acid with a polyepoxide modifier to form a thermoplastic composition, extruding the thermoplastic composition through a die, and thereafter passing the extruded composition through a die to form a fiber. Without intending to be limited by theory, it is believed that the polyepoxide modifier reacts with the polylactic acid and results in branching of its polymer backbone, thereby improving its melt strength and stability during fiber spinning without significantly reducing glass transition temperature. The reaction-induced branching can also increase molecular weight, which may lead to improved fiber ductility and the ability to better dissipate energy when subjected to an elongation force. To minimize premature reaction, the polylactic acid and polyepoxide modifier are first blended together at a relatively low temperature(s).Type: ApplicationFiled: August 13, 2010Publication date: February 16, 2012Applicant: KIMBERLY-CLARK WORLDWIDE, INC.Inventors: Vasily A.

Patent number: 8064203Abstract: A free standing film includes: i. a matrix layer having opposing surfaces, and ii. an array of nanorods, where the nanorods are oriented to pass through the matrix layer and protrude an average distance of at least 1 micrometer through one or both surfaces of the matrix layer. A method for preparing the free standing film includes (a) providing an array of nanorods on a substrate, optionally (b) infiltrating the array with a sacrificial layer, (c) infiltrating the array with a matrix layer, thereby producing an infiltrated array, optionally (d) removing the sacrificial layer without removing the matrix layer, when step (b) is present, and (e) removing the infiltrated array from the substrate to form the free standing film. The free standing film is useful as an optical filter, ACF, or TIM, depending on the type and density of nanorods selected.Type: GrantFiled: January 25, 2008Date of Patent: November 22, 2011Assignee: Dow Corning CorporationInventors: Carl Fairbank, Mark Fisher

Publication number: 20110277947Abstract: Cellulose nanofilaments from cellulose fibers, a method and a device to produce them are disclosed. The nanofilaments are fine filaments with widths in the sub-micron range and lengths up to a couple of millimeters. These nanofilaments are made from natural fibers from wood and other plants. The surface of the nanofilaments can be modified to carry anionic, cationic, polar, hydrophobic or other functional groups. Addition of these nanofilaments to papermaking furnishes substantially improves the wet-web strength and dry sheet strength much better than existing natural and synthetic polymers. The cellulose nanofilaments produced by the present invention are excellent additives for reinforcement of paper and paperboard products and composite materials, and can be used to produce superabsorbent materials.Type: ApplicationFiled: May 11, 2011Publication date: November 17, 2011Applicant: FPINNOVATIONSInventors: Xujun HUA, Makhlouf LALEG, Thomas OWSTON

Publication number: 20110281111Abstract: A template-free reverse micelle (RM) based method is used to synthesize pyrochlore nanostructures having photocatalytic activity. In one embodiment, the method includes separately mixing together a first acid stabilized aqueous solution including pyrochlore precursor A and a second acid stabilized aqueous solution including pyrochlore precursor B with an organic solution including a surfactant to form an oil-in-water emulsion. Next, equimolar solutions of the first and second acid stabilized oil-in-water emulsions are mixed together. Then, the mixture of the first and second acid stabilized oil-in-water emulsion is treated with a base to produce a precipitate including pyrochlore precursors A and B. After which, the precipitate is dried to remove volatiles. The precipitate is then calcined in the presence of oxygen to form a pyrochlore nanostructure, such as a bismuth titanate (Bi2Ti2O7) pyrochlore nanorod. The method of synthesizing the pyrochlore nanorod is template-free.Type: ApplicationFiled: May 11, 2011Publication date: November 17, 2011Applicant: Board of Regents of the Nevada System of Higher Education, on behalf of the University of Nevada,Inventors: Vaidyanathan Subramanian, Sankaran Murugesan

Publication number: 20110262749Abstract: The present invention enables easy manufacturing of a thermal insulating fine fiber and the like, for example, having a high degree of freedom in size and shape and excellent thermal insulating properties. In a manufacturing method according to the present invention, a first end of a preform constituted by bundling a plurality of pipes 1 is sealed, and suction of inner gas of each of the pipes is carried out from a second end side of the preform. By heating the preform with the internal pressure of each of the pipes being thus reduced from the first end side and drawing the preform, a fine fiber is made from the preform. While drawing the preform, by intermittently providing the fine fiber with sealing portions for sealing holes in the fine fiber, a thermal insulating fine fiber is manufactured.Type: ApplicationFiled: April 26, 2011Publication date: October 27, 2011Inventor: Eisuke Sasaoka
