Antimicrobial activity of copper sulfate and copper oxide embedded on polyurethane foam

Abstract

© 2018 Trans Tech Publications, Switzerland. CuSO4-deposited and CuO-deposited polyurethane foam (PUF) were fabricated in this study. Image analysis showed color transformation of the PUF from yellow to blue-green, which is indicative of the deposited CuSO4 particles on the substrate. Further color transformation of the material from blue-green to greenish-brown after soaking in NaOH suggest that the CuSO4 oxidized to form CuO, which was confirmed by the presence of CuO peaks during XRD analysis. SEM images also reveal the presence of CuO rods embedded in the PUF. The antibacterial activities of the CuSO4-and CuO-deposited samples against the gram-negative Escherichia coli bacteria were conducted.
