Abstract
Zinc oxide thin films on stainless steel substrates were fabricated via electrophoretic deposition at 150Vdc. The process of deposition was performed at different time intervals (1sec, 10sec, and 20sec) SEM micrographs showed increased thickness with from 20um to 120um. The photocatalytic activity of the deposited ZnO was examined against Staphylococcus aureus. Bacterial count (cfu/ml) was obtained after UV irradiation of coated and uncoated stainless steel. Results showed the bacterial count was significantly reduced from 22.76% to 51.81% with increased film thickness and UV irradiation. The films retarding effect on bacterial growth reveals promise of its suitability for medical applications and household use.
