Abstract

Polyimide (PI) nanocomposite reinforced with Fe₃O₄ nanoparticles (NPs) at various NPs loadings levels of 5.0, 10.0, 15.0, and 20.0 wt% were prepared. The chemical interactions of the Fe₃O₄ NPs/PI nanocomposites were characterized using Fourier Transform Infrared (FT-IR) spectroscopy. X-ray Diffraction (XRD) results revealed that the addition of NPs had a significant effect on the crystallization of PI. Scanning electron microscope (SEM) and the atomic force microscope (AFM) were used to characterize the dispersion and surface morphology of the Fe₃O₄ NPs and the PI nanocomposites. The obtained optical band gap of the nanocomposites characterized using Ultraviolet-Visible Diffuse Reflectance Spectroscopy (UV-Vis DRS) was decreased with increasing the Fe₃O₄ loading. Differential scanning calorimetry (DSC) results showed a continuous increase of T_g with increasing the Fe₃O₄ NPs loading. Some differences were observed in the onset decomposition temperature between the pure PI and nanocomposites since the NPs and the PI matrix were physically entangled together to form the nanocomposites. The contact angle of pure PI was larger than that of Fe₃O₄/PI nanocomposites films, and increased with increasing the loading of Fe₃O₄. The degree of swelling was increased with increasing the Fe₃O₄ loading and the swelling time. The dielectric properties of the nanocomposite were strongly related to the Fe₃O₄ loading levels. The Fe₃O₄/PI magnetic property also had been improved with increasing the loading of the magnetic nanoparticles.
