The Effects of Chemical Modification of Fe۳O۴ MNPs with PCL Chains onMechanical Properties of Polyurethane Magnetic Nanocomposites

Herein, Fe۳O۴ magnetic nanoparticles (neat MNPs) were synthesized and modified bypolycaprolactone chains (PCL-grafted MNPs). Moreover, polyurethane (PU) was synthesized and itsdifferent nanocomposites containing ۳ wt.% of neat and PCL-grafted MNPs were prepared throughthe solution casting method. The effect of these MNPs on the mechanical properties of SMPU wasstudied. The results showed that nanocomposites containing modified nanoparticles have higherYoung's modulus and tensile strength than those containing neat nanoparticles.
