摘要： A device and method are provided combining the thermal and mechanical attributes of two distinct materials: shape memory materials and super-cooled liquids (SCLs). In one example of the invention, the super-cooled liquid is contained within a shape memory polymer (SCL liquid is filled into a shape memory polymer tube), so that the heat released by the SCL when it is mechanically triggered to crystallize itself triggers the shape change of the shape memory polymer. The device is suitable as a reusable warmer, as a dental mold material, in medical applications where reusable heat packs are indicated, particularly for application to difficult contours, and for large deployable structures such as satellite antennae and temporary shelters.

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： A composite material containing polymeric nanofibers, themselves containing NO-donor molecules, imbibed with an elastomer matrix is permeable to both water and gas so that dissociation reactions in the presence of water releases NO gas in a sustained manner. The NO-donor nanofibers may be formed by synthesizing acceptable NO-donor molecules, blending such molecules in solution with PVP, PCL or PVAc, electrospinning the blend at relatively high voltage for form fiber mats, applying PDMS rubber to the fiber mat and crosslinking it. The resulting NO-releasing electrospun fiber composite may be used in medical devices such as catheters, stents, or vascular grafts, with the purpose of releasing nitric oxide within a controlled rate and for a sustained period of time, as well as other known medical applications for NO.
