Abstract
Zinc oxide films were fabricated on iron mesh substrate via electrophoretic deposition for Salmonella typhimurium inhibition. Different deposition voltage was performed at 25V, 50V and 75V for 20s. The SEM micrographs presented increasing thickness with voltage from 70 pm to 150 pm. The treatments performed to observe the inhibition property of ZnO were as follows: (a) with ZnO deposit; (b) UV exposure with ZnO deposit; and (c) with UV exposure. Results showed that UV-exposed ZnO-coated mesh deposited at 75V showed a bacteria reduction up to 40%. The ZnO-coated material, therefore, is capable of inhibiting bacterial growth thereby preventing the spread of Sahnonella typhimurium in the environment.
