Abstract
Antibacterial fabrics for use in medical textiles has been provided a useful weapon in the on-going fight against hospital-acquired infections. Generally, metal oxide nanoparticles(NPs) such as TiO2, ZnO and CuO have been applied on to cotton or synthetic fabrics. Recently sonochemical coating technology has been introduces for the purpose of developing antibacterial fabrics. The method showed high efficiency for a wide variety of NPs to be coated on various textile substrates. This study aims to deposit copper nanoparticles (Cu-NPs) on PET fabrics using ultrasound irradiation. The structure of Cu-NPs/PET-fabric composites was investigated by FE-SEM. The adhesion of Cu-NPs to the fibers is discussed with washing tests. The excellent antibacterial activity of the Cu-NPs/PET–fabric composite is expected and would be reported in successive work. Cu nanoparticles could be successfully deposited on PET fabrics through sonochemical coating technology using probe-type ultrasound irradiation. The deposition state of Cu-NPs on the fabrics were observed to be uniform by FE-SEM. The adhesion of Cu-NPs to the fabrics were evaluated as stable enough to provide performance of antibacterial activity after 5 times of washing according to a standard washing condition.
