Patent number: 10471648Abstract: 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.Type: GrantFiled: March 1, 2017Date of Patent: November 12, 2019Assignee: Syracuse UniversityInventors: Patrick Mather, Xiaofan Luo, Andrew M.

Patent number: 9533469Abstract: 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.Type: GrantFiled: December 22, 2009Date of Patent: January 3, 2017Assignee: Syracuse UniversityInventors: Patrick Mather, Xiaofan Luo
