  • Patent number: 10239788
    Abstract: A composition comprising thermoset polymer, shape memory polymer to facilitate macro scale damage closure, and means for molecular scale healing has the ability to repair structural defects by a bio-mimetic, close-then-heal process. The shape memory polymer serves to bring surfaces of a structural defect into proximity, after which the healing means moves into the defect and provides molecular scale healing. The means for molecular scale healing can be a thermoplastic, such as fibers, particles or spheres, which are heated to or above the thermoplastic's melting point, and then the composition is cooled below that melting temperature. The compositions can not only close macroscopic defects, but they can also do so repeatedly even if damage recurs in a previously healed/repaired area.

  • Patent number: 8585795
    Abstract: In accordance with the invention there are devices and processes for making ceramic nanofiber mats and ceramic filters for use in high temperature and in corrosive environments. The process for forming a ceramic filter can include electrospinning a preceramic polymer solution into a preceramic polymer fiber having a diameter from about 10 nm to about 1 micron and forming a preceramic polymer fiber web from the preceramic polymer fiber onto a collector. The process can also include pyrolyzing the preceramic polymer fiber web to form a ceramic nanofiber mat having a diameter less than the diameter of the preceramic polymer fiber, the ceramic nanofiber mat comprising one or more of an oxide ceramic and a non-oxide ceramic such that the ceramic fiber mat can withstand temperature greater than about 1000 ° C.

  • Publication number: 20130273283
    Abstract: Disclosed is a UV stabilized polyarylene sulfide composition, methods of forming the composition, and UV stabilized products that can be formed of the composition. The UV stabilized polyarylene sulfide composition can include a reactively functionalized polyarylene sulfide polymer in conjunction with a UV stabilizer. The reactivity of the polyarylene sulfide polymer is formed during melt processing via reaction of a reactively functionalized disulfide compound with a starting polyarylene sulfide. The reactivity of the polyarylene sulfide can encourage interaction between the polyarylene sulfide polymer and the UV stabilizer, which can improve dispersion of the UV stabilizer throughout the composition and improve miscibility between the polyarylene sulfide polymer and the UV stabilizer. Products can incorporate high concentrations of UV stabilizer and/or can be formed to very small cross sectional dimensions without phase separation between the UV stabilizer and the polyarylene sulfide.

  • Publication number: 20130244527
    Abstract: Disclosed are technical fibers and yarns made with partially aromatic polyamides and non-halogenated flame retardant additives. Fabrics made from such fibers and yarns demonstrate superior flame retardancy over traditional flame retardant nylon 6,6 fabrics. Further, the disclosed fibers and yarns, when blended with other flame retardant fibers, do not demonstrate the dangerous “scaffolding effect” common with flame retardant nylon 6,6 blended fabrics.
