利用具有六方柱状液晶相（ΦH）的半相侧链聚苯乙烯（P1）制备了一种热塑性高应变多形状记忆聚合物。在没有任何化学交联的情况下，P1可以在高应变下记忆多种临时形状，并表现出优异的形状固定性和形状恢复性。作为ΦH的构建单元，P1中的多链柱充当稳健的物理交联。
A thermoplastic high strain multishape memory polymer can be fabricated using a hemiphasmid side-chain polynorbornene (P1) with hexagonal columnar liquid crystalline (ΦH ) phase. Without any chemical crosslinks, P1 can memorize multiple temporary shapes with high strain and exhibit excellent shape fixity and shape recovery. As the building blocks of ΦH , the multichain columns in P1 act as robust physical crosslinks.
