In order to improve the mechanical properties of acrylic films, Poly methyl-methacrylate (PMMA)/ Aluminum oxide (Al 2 O 3 ) films are prepared following solution casting technique. The mechanical behavior of prepared films has been analyzed by employing Ultrasonic Pulse Echo method. The morphology of films is examined via XRD and SEM analysis. The synergetic effect is observed in films from obtained ultrasonic data. The elastic modulus is calculated and compared for better utilization. Author(s) Details Dr. A. R.

Solid polymer metal oxide films containing Poly (methyl-methacrylates) PMMA/Ferric oxide Fe 2 O 3 are synthesized following solution cast technique. Complexation and particle size are determined by XRD and SEM analysis. Ultrasonic and Dielectric characterization have been done by using Ultrasonic Pulse Echo method and LCR meter respectively. The dielectric behavior of PMMA/ Fe 2 O 3 films has been studied as a function of concentration, and at lower frequencies over the range 100 Hz - 25 KHz. A 7:3 PMMA/Fe 2 O 3 film have been found to posses optimal conducting and optical properties. The ultrasonic velocity is also found to be minimum in same film which may be attributed to maximum dissociation with least absorption in polymer matrix. Addition of Fe 2 O 3 thermally stabilizes PMMA matrix. Author(s) Details Dr. A. R. Bansod Acoustical Research Lab, PG Department of Physics, RTMNU, Nagpur, 992302440, India. Dr. O. P.
