Abstract
Abstract Shape memory epoxy resin has a high potential for applications in various fields such as space deployable structures and actuators. In order to meet the requirements of application and extend the materials' service life, it is highly desirable to develop a shape memory epoxy resin with good properties of shape memory, reprocessing, and self‐healing. In this work, a shape memory epoxy resin based on the orientable biphenyl mesogen and the dynamic siloxane is fabricated successfully via anion ring‐opening polymerization. The resulting epoxy resin exhibits excellent shape memory performance, good reprocessing ability, good self‐healing property, and triple shape memory effect (triple‐SME).
