Study the Rheological and Mechanical Properties of PVA/CuCl2 by Ultrasonic

Abstract

Some of physical properties of polyvinyl alcohol dissolves in distilled water had been studied before and after adding different weights of copper (II) chloride (CuCl₂), the Rheological properties shows that the densities variation are intangible and shear viscosity are responsible for reducing velocity, bulk modulus and transmittance the absorption coefficient of ultrasonic waves and relaxation amplitude are increasing with adding copper (II) chloride because there will be more molecules in solution and this lead to more attenuation against wave propagation.

Keywords: PVA solution, mechanical properties, rheological properties, ultrasound technique.
