Abstract
Metal nanowires are a 1D structure possessing distinct properties suitable for diverse applications. Copper nanowires (Cu NW) have garnered attention in recent times, particularly as an antibacterial material. Nevertheless, their utilization as a bandage or dressing material necessitates a suitable support, an aspect that remains largely unexplored. In this study, we have developed activated carbon fiber (ACF)-supported Cu NW using the chemical reduction and wet impregnation methods. Tested against Escherichia coli and Staphylococcus aureus, Cu NW/ACF exhibits 83 - 86% reduction in the bacterial growth. The improved antibacterial activity of the material is attributed to the relatively slow release of Cu ions from Cu NW, attributed to the Kelvin effect. Biocompatibility test confirms less than 1.5% hemolysis of erythrocytes, indicating the potential application of the composite as a bandage or dressing material.
