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 involves a new and better solution to the problems associated with the premature softening of PLA filaments in the additive manufacturing of three dimensional articles. It is based upon the finding that poly(lactic acid) filaments with high crystallinity offer much better resistance to heat-induced softening. The crystalline poly(lactic acid) filament of this invention can accordingly be used in the additive manufacturing of three dimensional articles without encountering the problems associated with premature softening, such as poor quality and printer jamming. The crystalline poly(lactic acid) filaments of this invention can also be used in additive manufacturing of three dimensional articles without compromising the quality of the ultimate product, reducing printing speed, increasing cost, or leading to increased printer complexity. This invention more specifically discloses a filament for use in three-dimensional printing which is comprised of crystallized poly(lactic acid), wherein said filament has a diameter which is within the range of 1.65 mm to 1.85 mm.

摘要： 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.

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.
摘要翻译： 本发明基于以下发现：活性炭可用于螯合可能存在于沥青和杂酚油组合物中的多环芳烃。 用活性炭处理沥青和杂酚油组合物相应地降低了这些组合物中游离多环芳烃的含量，其中将它们封存在其中或将其从组合物中除去。 被隔离后，多环芳烃被捕获在沥青或杂酚油组合物中，并且在正常加工成有用的工业产品期间不能被环境使用。 这种隔离降低了将人类和环境暴露于多环芳烃的风险，多环芳烃在制造过程中和产品的使用寿命期间可能会从沥青或杂酚油产品中自由迁移。 换句话说，多环芳烃被吸收到活性炭上，不能用于从环境的生物累积。
