In this article, a simple ultrasonic irradiation method for preparing novel poly(vinyl pyrrolidone)/poly(amide–imide)-SiO2 nanocomposites (PVP/PAI-SiO2 NC)s is reported. For this purpose, PAI-SiO2 NC as a filler was embedded in PVP. The presence of incorporated filler into the PVP matrix is established by Fourier transform infrared spectroscopy, X-ray diffraction, field emission scanning electron microscopy (FE-SEM), atomic force microscopy, and transmission electron microscopy (TEM). The filler has an average particle size of 10–20 nm as observed by TEM. The FE-SEM images show that the filler was uniformly dispersed in the polymer matrix. Thermogravimetric analysis results showed that the addition of filler favored the enhancement of thermal stability of PVP/PAI-SiO2 NCs.
