| Summary: | The permanent anti-mold protection of textile surfaces, particularly those utilized in the manufacture of outdoor sporting goods, is still an issue that requires cutting-edge solutions. This study attempts to obtain antifungal nanocoatings on four selected fabrics used in the production of high-mountain clothing and sleeping bags, and on PET foil as a model substrate, employing the cold plasma technique for this purpose. Three plasma treatment procedures were used to obtain such nanocoatings: plasma-activated graft copolymerization of a biocidal precursor, deposition of a thin-film matrix by plasma-activated graft copolymerization and anchoring biocidal molecules therein, and plasma polymerization of a biocidal precursor. The precursors used represented three important groups of antifungal agents: phenols, amines, and anchored compounds. SEM microscopy and FTIR-ATR spectrometry were used to characterize the produced nanocoatings. For testing antifungal properties, four species of common mold fungi were selected: <i>A. niger</i>, <i>A. fumigatus</i>, <i>A. tenuissima</i>, and <i>P. chrysogenum</i>. It was found that the relatively best nanocoating, both in terms of plasma process performance, durability, and anti-mold activity, is plasma polymerized 2-allylphenol. The obtained results confirm our belief that cold plasma technology is a great tool for modifying the surface of textiles to provide them with antifungal properties.
