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: 20110117296Abstract: The present invention relates to a pressure-sensitive adhesive composition, including an interpenetrating polymer network structure in a cured state and comprising a pressure-sensitive adhesive strength stabilizer; a polarizer; and a liquid crystal display. In the present invention, by using the stabilizer having a functional group capable of rapidly reacting with a multifunctional crosslinking agent, the change of the pressure-sensitive adhesive strength over time is quickly terminated right after preparation, thereby the pressure-sensitive adhesive strength is rapidly stabilized. The pressure-sensitive adhesive of the present invention has an excellent removability in a room-temperature or warming condition. Also, the pressure-sensitive adhesive can efficiently suppress light leakage, and has an excellent workability and durability in a high-temperature and/or high-humidity condition.Type: ApplicationFiled: July 1, 2009Publication date: May 19, 2011Applicant: LG CHEM, LTD.Inventors: Ki Seok Jang, In Cheon Han, Min Soo Park
