PCL/ZnO-PVA NCs were fabricated via ultrasonic irradiation, as a green method.
ZnO NPs were modified with PVA, as a biodegradable and biocompatible agent.
Surface modification of NPs increased their compatibility in the polymer matrix.
The effect of NPs content, on the various properties of the NCs was investigated.
TEM and FE-SEM images of the NCs verified their well dispersion in the matrix.
