Shape memory polymers (SMPs) are expected to play more and important roles in space-deployable structures, smart actuators, other high-tech areas. Nevertheless, because of the difficulties fabrication programmability temporary shape recovery, SMPs have not yet been widely applied real fields. It is ideal incorporate different independent functional building blocks into a material. Herein, we designed simple method four blocks: neat epoxy-based (neat SMEP) resin, an SMEP composited with Fe3O4 (SMEP-Fe3O4), multiwalled carbon nanotubes, p-aminodiphenylimide multicomposite, which region surfaces could be programmed language code patterns according preset command by imprint lithography. Then, aimed reprogram initially raised flat using programming mold that, when triggered stimulus process such as alternating magnetic field, radiofrequency 365 nm UV, direct heating, transform these codes information passed customer. The concept introduced here will available provide practical realize delivery.
