Abstract
in this paper, two novel Composites zinc phosphate/Polyvinyl alcohol (ZnP-PVA) and Zinc Phosphate/Polyvinyl alcohol/Carboxymethyl cellulose (ZnP-PVA/CMC) had been synthesized by a low-temperature and one-step ultrasonic-template assisted route. For characterization of samples, Scanning Electron Microscopy (SEM), X-ray diffraction (XRD), Transmission Electron Microscopy (TEM), Fourier-transform infrared spectroscopy (FTIR), Energy Dispersive X-Ray Analysis (EDAX), MIC/MBC and EIS were used. FTIR spectra of the composite confirmed the functional groups present in the composite and PVA/CMC/Zn2+ ions infraction and also SEM and TEM images showed the composites have a layered structure with rectangular microcrystals (2.8 mm width ZnP-PVA was able 100% to completely remove bacteria in the tested sample. As the results show, Anti-corrosion efficiency inhibitor ZnP-PVA is 92.8% at 2 h, 70.6% at 4 h, 68.0% at 24 h and aslo ZnP-PVA/CMC is 67.7% at 2 h, 45.6% at 4 h, 50.5% at 24h, has been investigated.
