Abstract

The antifungal properties of two silver-coated natural cotton fiber structures prepared using a supercritical carbon dioxide (scCO ₂) solvent were examined. Scanning electron microscopy confirmed that the scCO ₂ process may be used to produce cotton fiber textiles with uniform silver nanoparticle coatings. A version of the Kirby-Bauer disk diffusion test was used to assess the ability of these textiles to inhibit fungal growth. Cotton fabric samples modified with Ag(hepta) and Ag(cod)(hfac) exhibited measurable zones of inhibition. On the other hand, the uncoated fabric had no zone of inhibition. Possible applications of antifungal textiles prepared using scCO ₂ processing include use in hospital uniforms and wound dressings.
