| مستخلص: |
Polyurethane acrylate (PUA)–Ag/TiO2nanocomposites were synthesized through in situ polymerization. The well-dispersed Ag/TiO2nanorods serve as photoinitiator. Meanwhile, the PUA–Ag/TiO2nanocomposite films exhibit superior activity toward the photocatalytic degradation ofEscherichia coliunder UV light. The excellent UV curing and antibacterial activities can be ascribed to the synergistic effect of Ag and TiO2, which promotes the effective electron/hole separation and thus generates various reactive species. Thin films with these nanoparticles are more hydrophilic after UV illumination. And the antibacterial mechanism of the UV-curable PUA–Ag/TiO2nanocomposites was proposed. [ABSTRACT FROM AUTHOR] |
