  • Patent number: 9890258
    Abstract: A plastic film is produced by blending a polymer with particles encapsulating an oxidizing agent, such as hydrogen peroxide. Optionally, an “oxodegradable” and/or “oxo biodegradable” additive that promotes degradation of the polymer in the presence of oxygen may be blended into the plastic film. The presence of the oxidizing agent within the plastic film ensures degradation of an article of manufacture, e.g., a plastic bag, when it is disposed of in an anaerobic environment, such as a landfill. In some embodiments, the particles are microcapsules and/or nanocapsules each having a polymer shell encapsulating a core that includes the oxidizing agent. In some embodiments, the particles are microparticles and/or nanoparticles each having a matrix in which the oxidizing agent is encapsulated.

  • Patent number: 9890480
    Abstract: Poly-(caffeyl alcohol) (PCFA), also known as C-lignin, is a promising new source of both carbon fibers and pure carbon. PCFA can be used to produce carbon fibers by direct electrospinning, without blending with another polymer to reduce breakage. Analyses have shown that the carbon obtained from PCFA is superior to that obtained from other lignins. The fibers formed from PCFA are smoother, have a narrower diameter distribution, and show very low defects. The PCFA can be obtained by extraction from plant seed coats. Examples of these plants include the vanilla orchid, Vanilla planifolia, and Jatropha curcas. The fibers may be formed through electrospinning, although other methods for forming the fibers, such as extrusion with a carrier polymer, could be used. The fibers may then be carbonized to increase the carbon yield.
