Abstract: Shape memory polymers (SMPs) are a class of smart polymers that can recover from a temporary shape to an original shape under the action of external stimuli (light, temperature, and magnetic field). SMPs have been widely used in several applications such as soft robotic grippers, deployable structures for aircraft and spacecraft, intelligent medical devices ( magnetically sensitive) , and self- healing polymers. In this work, bio- based SMPs were prepared from copolymers of vanillin/ furfurylamine- based benzoxazine monomer (V- fa monomer) and polyglycerol polyglycidyl ether (PGPE). The incorporation of iron oxide nanoparticles (Fe3O4 NPs) as a magnetic filler into copolymers provided shape memory effects that could be induced by a high frequency alternating magnetic field in the range of 750- 1150 kHz. The effects of ratio between V- fa and PGPE in copolymers and content of Fe3O4 NPs on magnetic, dynamic mechanical, morphology, and shape memory properties of V- fa/PGPE copolymers were investigated. The results showed that glass transition temperature of copolymers could be increased from 42 to 72 °C by increasing V-fa content from 30 to 50 wt%. Under actuation by using alternating magnetic field, all specimens could recover from temporary shape to original shape and recovery time was drastically reduced from 78 to 7 s upon increased Fe3O4 NPs content from 1 to 10 wt%. In overall, the results suggested that V- fa/PGPE copolymers filled with Fe3O4 NPs have a great potential to be applied as magnetic-responsive SMPs
