Antimicrobial and Superhydrophobic CuONPs/TiO₂ Hybrid Coating on Polypropylene Substrates against Biofilm Formation.

ABSTRACT: Biofilm formation in common public places and hospitals is of great concern. Active antimicrobial coatings can prevent the formation of bacterial biofilms and the spreading of primary and secondary infections caused by contagious bacteria and viruses. In the present work, we report a simple spray coating process using copper oxide (CuO) nanoparticles (NPs) dispersed in a titanium dioxide (TiO₂) sol, where CuONPs act as the active antimicrobial agent and TiO₂ as the inorganic binder. Homogeneous CuONPs/TiO₂ coating was obtained on polypropylene substrates by spraying the CuO/TiO₂ sol using a commercial air gun, followed by drying at 80 °C. The amount of CuONPs loading in the coating was adjusted by controlling the number of coated layers. CuONPs a
