Publication number: 20150344690Abstract: A two-way shape memory polymer composite material is provided, which comprises two interpenetrating network polymers, wherein one polymer is a shape memory polymer made of crystalline cross-linked polymer, the other one is a cross-linked elastomeric material. The composite material is formed by interpenetration of two network polymers, wherein one network polymer will shrink under heating and the other network polymer acts as the segment for energy storage. When the first polymer network shrinks under heating, it presses the second polymer network, while the heating is cancelled the pressed second polymer network will enforce the first polymer network to recover the original shape, therefore it has the behavior of two-way shape memory.Type: ApplicationFiled: August 7, 2014Publication date: December 3, 2015Applicant: POLYU BASE (SHENZHEN) LIMITEDInventors: Jinlian HU, You WU
