Silver NPs Reinforced the Structural and Mechanical Properties of PVA-PAAm-PEG Nanocomposites

What is it about?

The results that obtained show that most of the physical properties affected by the increasing of the ratio of Ag weight percentages. Most of the results have improved and presented the values of higher than normal with the addition of Ag. Where, the addition of nanosilver increased the U/S velocity and the ultrasonic absorption coefficient of the polymer-based Ag NPs, so increased the density and viscosity. Furthermore, Ag NPs led to a decrease in compressive values of the prepared films, therefore more tolerable to environmental conditions and can be usage in the external environment, so it can be used in various industrial applications. The viscosity increased up to 107 %. Additionally, It was found that the best ratio of Ag NPs percentage weight is (0.04 wt.%), which showed the best mechanical results. The mechanical properties enhanced by the addition of Ag NPs and this clear appear in U/S velocity and bulk modules. Whereas Ag NPs weight percentage of (0.01 wt.%) resulted in a decrease in mechanical properties. (PVA-PAAm-PEG) blend films have been successfully prepared by dry casting technique at thickness of (950 nm), also the Ag NPs diffuse inside the polymer blend with agglomerate increasing of the amounts of Ag NPs. (PVA-PAAm-PEG) blend films is a good media for absorb U/S wave. The blend solutions have been succeed to be anti- scattering medium instead of sonar and echo gel because of easy to preparation, cheap, harm of skin, conduct to electricity and local production.
