Mechanical Properties of Xanthan Cellulose Gum-TiO2 Composite

Some of physical properties of xanthan cellulose gum (Xn) dissolves in distilled water had been studied at different concentrations (0.1, 0.2,…, 0.8)% g/mL before and after adding (0.25and 0.5) g of (TiO2) for all concentrations. The mechanical properties such as ultrasonic velocity has been measured by ultrasonic waves system at frequency( 25 kHz) and other mechanical properties have been calculated such as absorption coefficient of ultrasonic waves, relaxation time, relaxation amplitude, specific acoustic impedance, compressibility and bulk modules. The results show that all these properties are increase with the increasing of the polymer concentration except compressibility, also, the results show that when adding (TiO2) these properties are increasing except compressibility is decreasing. But adding (TiO2) to (Xn) enhances these properties.
