Abstract

In this work, the miscibility studies of carboxymethylcellulose/poly (vinyl alcohol) CMC/PVA blends were
studied by viscosity, refractive index, density, and ultrasonic interferometer techniques. The values of molecular
interaction parameters such as ∆B, μ, and α were revealed that CMC/PVA blend is miscible when the PVA content
is higher than 50%. The films of CMC/PVA blends were characterized by Fourier-transform infrared techniques.
ZnO nanoparticles were prepared by precipitation method and incorporated to CMC/PVA blends films. The micro
structural properties of the ZnO nanoparticles incorporated to CMC/PVA blend films were characterized using
X-ray diffraction techniques. Immiscible CMC/PVA polyblends were found to be miscible at all compositions of
CMC/PVA blends when ZnO nanoparticles incorporated to polymer composite films.
