Three distinct polymers were used as model polymers in this study: poly (vinyl alcohol) (PVA), polyacrylamide (PAM), and poly (ethylene glycol) (PEG). These polymers were employed to make nanocomposites films utilizing solution and dry casting techniques with varied loading ratios of Silver nanopowders (AgNPs) of (0.1, 0.2, and 0.4 wt. percent). The films were of varying thicknesses (950 nm). The diffusion of NPs among the gaps of polymer mix particles was determined using optical microscopy (OM). The polymers and Silver nanopowders (AgNPs) created an important interfacial contact, as evidenced by Fourier-transform infrared spectra. In nanocomposites, the most functional group of polymer and nanoparticle. Using the ultrasound technique (U/S), the mechanical characteristics of each film were measured and estimated. The velocity of the U/S wave was calculated using the frequency (40 kHz) of the film thickness (950 nm). Except for compressibility, mechanical characteristics improved as the number of Ag NPs increased. Doping with AgNPs had a considerable impact on the U/S coefficients. The resulting blend gels demonstrate these new nanocomposites as potential materials for a wide range of applications, and they were used in medical applications instead of U/S sonar and echo gel.
