Polymer nanocomposite thin film of polysulfone with different concentration of ZnO was prepared by solution grown technique. This paper presents a study on the structural and thermal properties of ZnO filled Polysulfone (PSF) nanocomposites. The structural morphology of the resulting nanocomposites was investigated by X-ray diffraction (XRD), Scanning electron microcopy (SEM), and Atomic force microscopy (AFM). Thermal properties of PSF nanocomposites samples were investigated by Differential thermal analysis, Thermal gravimetric, and Differential thermal gravimetric. Structural result shows that the ZnO nanofiller with different mass% in polymer matrix cause the significant variation of lattice spacing, crystallite size, and percentage crystallinity. XRD result shows that the amorphous behavior of PSF (Pristine) is increasing with incorporation of ZnO nanoparticle in PSF matrix. The SEM and AFM images show the change in structural morphology of PSF due to incorporation of ZnO nanoparticles. The thermal analysis result shows that the significant thermal degradation of polysulfone nanocomposites due to catalytic behavior of ZnO nanoparticles.
