Abstract

Researches show that properties of semiconductor materials such as electrical, optical and antibacterial properties can be improved in the nanoscale. Among the semiconductor materials , zinc oxide with excellent electronic properties has been considered extremely. Application and properties of Zno nanoparticles depends on the size and morphology. In the present work, Zno Nanoparticles (NPs) were prepared by sonochemical method at a constant temperature and were applied on to the 100% cotton woven fabric using Insitu method. The results show that nanoparticles with average sizes of 20-100 nm with different morphologies were created on the surface of samples. Synthesis of ZnO-NPs were varied in the morphological transformation by changes in zinc acetate concentration. Characterizations were carried out, Scanning electron microscopy (SEM) and Spectrophotometery. The antibacterial activities of the fabrics were assessed semi-quantitatively by the coloneis count method. The results show that the finished fabric demonstrated significant antibacterial activity against S.aureus in antibacterial test.
