Publication number: 20120213969Abstract: 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: ApplicationFiled: February 21, 2012Publication date: August 23, 2012Applicant: SYRACUSE UNIVERSITYInventors: Patrick Mather, Pine Yang, Xiaofan Luo, Andrew M.

Publication number: 20120208916Abstract: The present invention relates to compounds and materials that reduce the accumulation of microorganisms on a surface by interfering with the attachment of the organisms to the surface. The compounds and materials of the present invention are thus useful in preventing the formation of biofilms. The compounds of the present invention may be either adhered to a surface or integrated within a polymer. Surfaces coated by the present invention are resistant to biofilm formation, in part due to the smoothness of the surface coated with the present invention.Type: ApplicationFiled: May 25, 2011Publication date: August 16, 2012Inventors: T.
