“…In addition, the brittleness problem of CE has to be tackled to ensure longer service life. Although thermoplastics, 6 rubber elastomers, 7 hyperbranched polymers 8 and inorganic nanofillers 9,10 prevent such an issue, they greatly damage other properties. Typically, organic modifiers tend to deteriorate the thermostability and strength of CE, while inorganic fillers not only increase the processing difficulty but also increase the dielectric constants of polymer matrixes due to their agglomeration behaviour.…”

In recent years, there has been rapid development in the field of shape memory materials with active deformation performance. However, bismaleimide, a widely used thermosetting material in aerospace, has been largely overlooked in shape memory applications. This work presents the synthesis of a molecule containing an alkene bond adjacent to an oxygen atom. Through molecular design, a one‐time reaction between this specialized molecule and the bismaleimide molecule is successfully achieved, facilitated by the steric hindrance effect. Therefore, a new series of shape memory bismaleimide materials are obtained. By introducing a diamine to adjust the chain length, the properties of material are further improved, resulting in increasing static modulus by 506 times. The synthesized materials exhibit a broad glass transition temperature (Tg) range exceeding 153 °C, remarkable stiffness tunability. Notably, in the synthesis process of this materials series, the disulfide bonds are introduced, which facilitates the realization of self‐healing and reprocessable functionalities in the resulting thermosetting materials. This significant advancement lays a solid foundation for the future recycling and reuse of aircraft, satellites, and other equipment, offering promising prospects for enhancing sustainability and efficiency within the aerospace industry.
