Antibacterial and antiviral activities of transparent PVA coating films prepared by using solutions containing eluted ions from rare earth iodates
After powders of three rare earth iodates (Ce(IO3)4, Ce(IO3)3, δ-La(IO3)3) were dispersed in water, the constituent ions were eluted. After filtration, polyvinyl alcohol was dissolved in the filtrated solution. Then the solution was flow-coated to form coating films on glass substrates. The obtained coating films exhibited high transmittance in the visible wavelength range. IO3− was confirmed from the IR spectra measured using the ATR method. Fine precipitates were observed in the coating. The amount was greater on the surface than inside. The coating films prepared from Ce(IO3)3 and δ-La(IO3)3 possessed high antibacterial and antiviral activities against Escherichia coli, Staphylococcus aureus, bacteriophage Qβ, and bacteriophage Φ6 in the dark. Moreover, they inactivated viruses adsorbed from the gas phase.
