Abstract

Lanthanide-doped Fe3O4 nanoparticles were synthesized and functionalized via electrodeposition method using which gadolinium cations (Gd3+) were exchanged partially with Fe3+ in the ferrite lattice. Polyethylene glycol (PEG) was grafted onto the surface of Fe3O4 and Gd-doped Fe3O4 to study its potential for epoxy curing. X-Ray diffraction (XRD) and Fourier-transform infrared spectroscopy (FTIR), field-emission scanning electron microscopy (FE-SEM), and vibrating sample magnetometry (VSM) confirmed successful synthesis, and bulk- and surface modification of Fe3O4 and Gd-Fe3O4 and PEG-Gd-Fe3O4. Nonisothermal differential scanning calorimetry (DSC) on samples containing 0.1 wt.% of nanoparticles was indicative of Poor cure for epoxy/Fe3O4 and epoxy/Gd-Fe3O4, while Excellent cure for epoxy/PEG-Gd-Fe3O4, demonstrating promising role of Gd in epoxy ring opening. © 2019
