Shape memory main-chain smectic-C elastomers are described, as are methods for their preparation and monomers used in such methods. The elastomers are prepared by hydrosilylation of a reaction mixture including a liquid crystalline diene, a crosslinking agent, and a bis(silyl hydride) compound. The elastomers exhibit shape-memory properties and spontaneously reversible shape changes. They are useful for fabrication of shape memory articles including, for example, implantable medical devices, contact lenses, reversible embossing media, and Fresnel lenses.
本文描述了形状记忆主链液晶C相弹性体,以及用于制备这些弹性体的方法和用于这些方法的单体。通过氢硅化反应混合物制备弹性体,包括液晶二烯,交联剂和双(硅烷氢)化合物。这些弹性体具有形状记忆性能和自发可逆形状变化。它们可用于制造形状记忆制品,例如可植入医疗器械,隐形眼镜,可逆压花介质和菲涅耳透镜。
