The bio-based shape memory polymers have generated immense interest as advanced smart materials. Mesua ferrea L. seed oil-based hyperbranched polyurethane (HBPU)/Fe3O4 nanocomposites were prepared by the in-situ polymerization technique. The transmission electron microscopy confirmed the homogeneous distribution of the Fe3O4 nanoparticles in...
