In the preparation of shape memory composites, the dispersion of ferric oxide Fe₃O₄ nanoparticles within the polymer matrix is crucial. However, the agglomeration of nanoparticles can often occur, leading to a decrease in mechanical properties and heating rate. This paper focused on modifying Eucommia ulmoides gum (EUG)/Fe₃O₄ composites with zinc methacrylate (ZDMA) to create EUG/Fe₃O₄/ZDMA magnetic and thermal dual response shape memory composites. The effects of varying ZDMA content on the mechanical properties, heating rate, magnetic response shape recovery rate and dispersion state of Fe₃O₄ nanoparticles of EUG/Fe₃O₄/ZDMA composites were investigated. The results indicate that the agglomeration of Fe₃O₄ nanoparticles significantly improves with increasing ZDMA content. The tensile strength of the EUG/Fe₃O₄/ZDMA composite is increased from 16.7 MPa to 23.5 MPa, with a notable 40.7% increase observed in the EUG/Fe₃O₄/ZDMA composite. DMA testing demonstrates that the shape fixation rate and shape recovery rate of EUG/Fe₃O₄/ZDMA composites are above 97% over three cycles. As the increase of ZDMA content, the heating rate of EUG/Fe₃O₄/ZDMA composite material in the alternating magnetic field increases, allowing for fast non- contact heating, and achieving shape recovery in as little as 27 s.
