Synthesis, characterization and USW sensor of PEO/PMMA/PVP doped with zirconium dioxide nanoparticles

The piezoelectric phenomena uses in various helpful applications, such as printing of piezoelectric inkjet, the detection of sound and the production of high voltage electricity in different electronic devices. In present research, polyethylene oxide (PEO), poly(methyl methacrylate) (PMMA) and poly(N-vinyl pyrrolidone) (PVP) were separately dissolved in deionized water. These polymers were mixed with ratio of 0.6:0.2:0.2 wt%, respectively before loaded with 0.0, 0.02, 0.04 and 0.06 wt% of zirconium dioxide nanoparticles (ZrO(2)NPs) via casting method to prepare nanocomposite (NCs) films. The optical microscope (OM) showed good diffused of the NPs into matrix with homogenous distribution. The functional groups of k1 specimen were diagnosed via Fourier transformation infrared (FTIR). The ultrasonic wave (USW) properties were studied for k1 specimen with various frequencies (25, 30, 35, 40 and 45) kHz. The USW coefficients were clearly affected by the frequency varied. The USW coefficients decreased with increasing the frequency except the compressibility. The dielectric constant of the k1 sample was notable improved up to 85% with increasing of applied load. The k1 specimen was succeeded to be used as USW sensor. New NCs film presented as promising material for wide electrical and mechanical applications.
