摘要： 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.

摘要： 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.

摘要： 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. In other words, the polycyclic aromatic hydrocarbons are absorbed onto the activated carbon and are not available for bioaccumulation from the environment.

摘要： An amorphous, optically transparent, colorless shape memory assisted self-healing coating for optical glassware applications that uses a combination of surface shape memory and self-healing properties to repair damaged sites on glass substrates when exposed to a thermal stimulus. The coating includes a miscible combination of a network polymer and a linear polymer having glass transition temperate between room temperature and about 40 degrees C. The coating can be used for corrective eyewear, for windshields and windows in automobiles and motorcycles, as well for as optical coatings wherever needed.
