Abstract

Ultrasound irradiation was used for anchoring silver nanoparticles with an average size from 10 to 50 nm onto the surface of acrylonitrile–butadiene–styrene (ABS) sheets 1 mm thick. The sonochemical reduction was carried out under argon at room temperature. Silver nanoparticles were obtained and deposited on the ABS surface by the irradiation of a mixture containing ABS plaques, silver nitrate (AgNO3), ethylene glycol and water. Reaction conditions such as temperature, AgNO3 concentration and irradiation time were controlled to achieve the deposition of silver nanoparticles onto the surface of ABS sheets. Nano silver coated ABS samples were characterized by X-ray diffraction, transmission and scanning electron microscopy, Raman spectroscopy and antimicrobial activity, specifically against the fungus, Aspergillius niger, and the bacterium, Escherichia coli. The observed results may be applied in the design of industrial ABS sheets with antimicrobial characteristics.
