Abstract
The PVA/TiO2 composite polymer membranes were prepared by a sol-Gel casting method, the weight
of PVA is constant (1gm) while the TiO2 powder ratios were (0.
01, 0.
02, 0.
03, 0.
04, 0.
05) gm.
In order
to evaluate the mechanical properties of PVA/TiO2 composite the ultrasonic measurements were
performed at the samples , these properties are ultrasonic velocity, compressibility, acoustic impedance,
relaxation time, bulk modulus, shear viscosity and density were analyzed at different frequencies
(25,30,35,40) KHz , another acoustic mechanical properties were measured and calculat
