Abstract
This work presents the preparation and characterization of hybrid organic–inorganic optically active poly(amide–imide)/nano–Fe3O4 composites with different amount of modified Fe3O4 nanoparticles as new nanocomposites by ultrasonic irradiation and characterized by Fourier transform infrared spectra, X-ray diffraction, scanning electron microscopy (SEM), thermogravimetric analysis and vibrating sample magnetometry. The surface of Fe3O4 nanoparticles was modified with 3-aminopropyltriethoxyl silane because of the homogeneous distribution of nano-Fe3O4 in polymer matrix, which the SEM results confirmed that the Fe3O4 nanoparticles were dispersed uniformly in polymer matrix. Furthermore, as compared with pure polymer, thermogravimetric analysis data indicated an improvement of thermal stability of nanocomposites.
