Preparation, characterization and surface morphology of novel optically active poly(ester-amide)/functionalized ZnO bionanocomposites via ultrasonication assisted process

► Preparation of new PEA/ZnO bionanocomposites using modified ZnO nanoparticles with KH570 via ultrasonic as a versatile tool for the synthesis of bionanocomposite polymers. ► The resulting bionanocomposites were fully characterized by various techniques such as FT-IR, XRD, TGA and their morphology was studied by FE-SEM, AFM and TEM analyses. ► All data indicate that the nanoparticles were dispersed homogeneously in PEA matrix on nanoscale. ► Due to the existence of amino acid in the backbone of obtained PEA, it is predictable to be biodegradable and biocompatible. Also because the ZnO nanoparticles is environmentally friendly so it would be suitable to name these nanocomposites, as PEA/ZnO bionanocomposite polymers.
