Resumo
Poly(urethane-imide)/Fe3O4@SiO2–NH2 nanocomposites were synthesized by the reaction of 4,4′-diphenylmethane diisocyanate (MDI), polypropylene glycol (PPG), 4,4'-(hexafluoroisopropylidene) diphthalic anhydride and Fe3O4@SiO2–NH2 nanoparticles in propylene carbonate (PC) as an alternative green solvent. Poly(urethane-imide)s combined with Fe3O4@SiO2–NH2 nanoparticles (NPs) at various NPs ranging from loadings levels of 0.5 and 3.5 pbw were prepared and characterized by fourier transform infrared spectroscopy (FT-IR), proton nuclear magnetic resonance spectroscopy (1H NMR), thermogravimetric analysis (TGA), X-ray diffraction (XRD) and vibrating sample magnetometery (VSM). The results showed the performances of Fe3O4@SiO2–NH2 nanoparticles in improving of thermal resistance and magnetic properties of PUI/Fe3O4@SiO2–NH2 in comparison with pristine poly(urethane-imide).
