摘要

The immobilization of nanoparticles (NPs) onto cotton fiber (CF) is a promising method for preparing antimicrobial textile, but NPs on the CF surface will leach out after several washing cycles, which leads to the deterioration of antimicrobial property and environmental pollution. Herein, to facilitate the penetration of Cu2+ ions into the interior of fibers, the treatment of CF using NaOH solution mixed with Cu2+ was proposed. Furthermore, hydrophobic and antimicrobial CF was prepared by in situ reduction of Cu2+ to cuprous oxide (Cu2O) using honeysuckle (Lonicera japonica Thunb) extract, followed by immersion in stearic acid (SA) ethanol solution. Even if the initial Cu2+ concentration was as low as 0.008 mol/L, the antimicrobial rates of the prepared hydrophobic Cu2O-cotton fabric (Cu2O-CF@SA) against Escherichia coli (E. coli), Staphylococcus aureus (S. aureus), and Candida albicans (C. albicans) were as high as 99.99%. Moreover, the prepared Cu2O-CF@SA also displayed excellent mechanical robustness and laundering durability, maintaining over 92% antimicrobial activity against E. coli and S. aureus after 50 tap-peeling cycles or 20 laundering cycles. The outstanding property of Cu2O-CF@SA offers great potentiality in antimicrobial fabric applications such as medical textiles (surgical gowns/masks), wound dressings, sportswear, and so on. This work provides an innovative method for the preparation of Cu2O using honeysuckle extract as green reductant for developing CF with durable antimicrobial activity.
