AB  - A novel and favorable antibacterial agent as a combination of copper nanoparticles (CuNPs) and polypyrrole (PPy) is presented. By simple in situ polymerization method, copper/polypyrrole (Cu/PPy) nanocomposite with spherical CuNPs, around 25 nm in diameter, uniformly dispersed throughout PPy matrix with granular morphology, was characterized and subjected to determination of antibacterial activity toward bacteria Escherichia coli and Staphylococcus aureus. Knowing that when acting alone, CuNPs and PPy have already shown antimicrobial responce, their mutual and synergetic engagement against bacteria in this survey is somewhat expected. After a twenty-four-hour interaction with S. aureus, already 2 ppm of Cu/PPy with only 9.45 wt% content of Cu is acting almost completely cidal, with 99.17% of bacterial growth inhibition. Such nanocomposite could easily find application in water disinfection, soil sterilization and food preservation.

AB  - This study discusses the possibility of engineering the multifunctional textile nanocomposite material based on the polyester (PES) fabric modified with colloidal Ag and TiO2 nanoparticles (NPs). Namely, encouraging results on the effects of TiO2 and Ag NPs separately applied to textile materials in our previous studies were the basis for an assumption that combined treatment with Ag and TiO2 NPs may bring multifunctional textile nanocomposite materials with desirable UV protective and antimicrobial effects. The antimicrobial activity of differently modified PES fabrics was tested against Gram-negative bacterium E. coli, Gram-positive bacterium S. aureus and fungus C. albicans. The efficiency of UV blocking was evaluated by determining the UV protection factor (UPF) of PES fabrics. The effect of Ag NPs on the photoactivity of TiO2 NPs deposited onto the PES fabrics was tested by degradation of methylene blue in aqueous solution under UV illumination. The total content of Ag and Ti in the PES fabrics was determined by atomic absorption spectroscopy. The morphology of PES fibers was followed by SEM.

The order of Ag and TiO2 NPs loading affects the antimicrobial efficiency of PES fabrics. The fabrics provide maximum UV protection independently of the order of Ag and TiO2 NPs loading. Ag NPs positively influenced the photodegradation activity of TiO2 NPs and total photodegradation of methylene blue under UV illumination was achieved after 24 h.

AB  - The aim of this study was to highlight the possibility of using the air RF plasma for fiber surface activation that can facilitate the deposition of silver nanoparticles from colloid onto the polyester fabrics and thus, enhance their antibacterial properties. The deposition of silver nanoparticles caused significant morphological changes as well as the color change of polyester fabrics. Untreated polyester fabrics and polyester fabrics activated by air RF plasma, both, subsequently modified by silver nanoparticles exhibited excellent antibacterial properties against Gram-negative bacterium E. coli and Gram-positive bacterium S. aureus. However, polyester fabrics activated by plasma provided better laundering durability of achieved effects.
