Electromagnetic wave (EMW) induction of shape memory polymers (SMPs) composites with multifunctional inorganic fillers is a high efficiency, uniform and non-contact method. Herein, shape memory effect of the ternary BCN/Fe3O4/PCL composites induced by EMW are explored. The components of Fe3O4 and BCN nanotubes are served as wave-absorbing materials. Electromagnetic properties and EMW absorption performance of BCN/Fe3O4/PCL are discussed in more detail. The EMW absorbed by BCN/Fe3O4/PCL is dissipated by dielectric loss and magnetic loss. The shape memory mechanism of the BCN/Fe3O4/PCL is based on Fe3O4 and BCN nanotubes dissipating absorbed EMW energy into heat to boost the temperature of the composites, thereby responding to EMW remote controlling. This work paves a new direction for SMPs induced by EMW as potential candidates in the field where shape recovery restricted space.
