A Green Route for the Synthesis of Alanine-based Poly(amide-imide) Nanocomposites Reinforced with the Modified ZnO by Poly(vinyl alcohol) as a Biocompatible Coupling Agent

The objective of this article was to fabrication and characterization of novel optically active poly(amide-imide)/zinc oxide nanocomposites (PAI/ZnO NCs) with different modified ZnO nanoparticles (NPs) contents under ultrasonic irradiation technique. For better dispersion of ZnO NPs in a polymer matrix, their surface was modified with poly (vinyl alcohol) (PVA) as a coupling agent. Effects of PVA modifier on dispersity of NPs, morphological structures and thermal stability of the obtained NCs were studied by several techniques. According to the transmission electron microscopy (TEM) images of the NC, the average diameter of particles was around 7 to 15 nm in the PAI.
