  • Patent number: 9533469
    Abstract: A self-healing product having a shape memory component and a healing component interpenetrating the shape memory component to form a fibrous microstructure. The healing component is selected so as to diffuse into a defect when the area of the product with the defect is subject to a treatment. The components may be selected so that applying heat at a temperature at or above a melting temperature (Tm) and/or a glass transition temperature (Tg) for one or both of the shape memory component and the healing component causes shape memory transition and diffusion by the healing component. The self-healing product can form a coating or material layer to protect a substrate while also providing the healing properties responsive to the treatment.

  • Patent number: 9249305
    Abstract: This invention is based upon the discovery that activated carbon can be used to sequester polycyclic aromatic hydrocarbons that may be present in asphalt and creosote compositions. The treatment of asphalt and creosote compositions with activated carbon accordingly reduces the level of free polycyclic aromatic hydrocarbons in such compositions by sequestering them therein or removing them from the composition. After being sequestered the polycyclic aromatic hydrocarbons remain trapped in the asphalt or creosote composition, and are not available to the environment during normal processing into useful industrial products. This sequestration reduces the risk of exposing humans and the environment to the polycyclic aromatic hydrocarbons which would otherwise be free to migrate from the asphalt or creosote product during manufacturing and the service life of the product.

  • Patent number: 8683798
    Abstract: Embodiments of a product such as a stimuli-responsive product can comprise a shape memory component and a nanofiber component that forms a fibrous microstructure or network. The resulting product can be responsive to stimuli, such as electrical stimuli, in a manner that cause the product to deform, deflect, and rebound. In one embodiment, the product can comprise an epoxy and a continuous non-woven nanofiber, the combination of which provides a product with enhanced actuation speed.

  • Publication number: 20120213969
    Abstract: A functionally graded shape memory polymer (SMP) that has a range of transition temperatures that are spatially distributed in a gradient fashion within one single article. The SMP is formed by post-curing a pre-cured glassy SMP in a linear temperature gradient that imposes different vitrification temperature limits at different positions along the gradient. Utilizing indentation-based surface shape memory coupled with optical measurements of photoelastic response, the capability of this material to respond over a wide range of thermal triggers is correlated with the graded glass transition behavior. This new class of SMP offers great potential for such applications as passive temperature sensing and precise control of shape evolution during a thermally triggered shape recovery.

  • Publication number: 20110003159
    Abstract: Embodiments of a self-healing product comprise a shape memory component and a healing component interpenetrating the shape memory component to form a fibrous microstructure. This microstructure can facilitate healing and mending mechanisms, wherein in one embodiment the healing component is selected so as to diffuse into a defect when the area of the product with the defect is subject to a treatment. This treatment can vary the temperature of the self-healing product, with the temperatures in one example being at or above a melting temperature (Tm) and/or a glass transition temperature (Tg) for one or both of the shape memory component and the healing component. The self-healing product can also comprise a substrate so that deposition of one or more of the shape memory component and the healing component onto the substrate can form a coating or material layer the likes of which can protect the subjacent substrate while also providing the healing properties responsive to the treatment.
