The development of ligand-stabilized nanoparticles is critical to advancements in additive manufacturing, high
density magnetic memory, electromagnetic interference shielding, and medicinal purposes. This study focused
on incorporating mono-dispersed magnetite (Fe3O4) nanoparticles in various polymers (polystyrene, polyimide,
and lower molecular weight varieties) with the goal of increasing the physical, magnetic, and dielectric
properties of the matrix. Magnetite was chosen primarily for its ease of synthesis, extensive literature presence,
negligible hysteresis, and low magnetic moment. In conjunction with fatty-acid-surface-modification, the
magnetite exhibited stability in both solution and the dried powder form. This property made it possible for
even distributions in polymer media when thin films and composite filaments were manufactured. The magnetic
properties of this composite system allowed for soft magnetic behavior that is influe
