Photocatalytic Efficiency and Antifungal Effects of Cotton Treated with TiO2 Nanoparticles
The aim of this research was to prepare photocatalytic textiles by depositing TiO2/ polyacrylic binder dispersions by the pad dry process and on ultrasound bath. The SEM image reveals that all fabrics, regardless the treatment conditions are coated with particles having different shapes and sizes dependent on the binder and titanium dioxide concentration and treatment method. The photocatalytic efficiency is strongly dependent on type and concentration of dyes, being very fast at low concentration and slow at high concentrations, where blocked TiO2 surface is unable to generate reactive species. The materials show good antimicrobial activity against the Trichophyton interdigitale fungal strain.
