Abstract
ABSTRACTIn 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.
