AB  - Growing demand for sustainable and green technologies has turned industries and research toward the more efficient utilization of natural and renewable resources. In an effort to tackle this issue, we developed an antibacterial textile nanocomposite material based on cotton and peat fibers with immobilized Cu-based nanostructures. In order to overcome poor wettability and affinity for Cu2+-ions, the substrate was activated by corona discharge and coated with the biopolymer chitosan before the in situ synthesis of nanostructures. Field emission scanning electron microscopy (FESEM) images show that the application of gallic or ascorbic acid as green reducing agents resulted in the formation of Cu-based nanosheets and mostly spherical nanoparticles, respectively. X-ray photoelectron spectroscopy (XPS) analysis revealed that the formed nanostructures consisted of Cu2O and CuO. A higher-concentration precursor solution led to higher copper content in the nanocomposites, independent of the reducing agent and chitosan deacetylation degree. Most of the synthesized nanocomposites provided maximum reduction of the bacteria Escherichia coli and Staphylococcus aureus. A combined modification using chitosan with a higher deacetylation degree, a 1 mM solution of CuSO4 solution, and gallic acid resulted in an optimal textile nanocomposite with strong antibacterial activity and moderate Cu2+-ion release in physiological solutions. Finally, the Cu-based nanostructures partially suppressed the biodegradation of the textile nanocomposite in soil.

AB  - A novel impregnation process for the fabrication of cotton nanocomposite with strong antimicrobial activity against antibiotics-resistant bacteria and yeast was developed. The impregnation process includes the sol-gel treatment of fabric with (3-aminopropyl)triethoxysilane in the first step, and synthesis of the CuO/Cu2O nanoparticles (NPs) on the fabric surface in the second step. The in situ synthesis of the CuO/Cu2O NPs was based on the adsorption of Cu2+-ions by the introduced amino groups of the sol-gel coating. The adsorbed Cu2+-ions are subsequently reduced in the alkaline solution of NaBH4. X-ray diffraction measurements confirmed the formation of CuO/Cu2O NPs. Scanning electron microscopy and atomic absorption spectrometry analyses indicate that the particle size, agglomeration, and amounts of synthesized NPs were highly affected by the initial concentration of CuSO(4)solution. The toxicity of nanocomposites to human keratinocytes (HaCaT) and antimicrobial activity against Gram-negativeEscherichia coliATCC 25922,E. coliATCC BAA 2469, andKlebsiella pneumoniaeATCC BAA 2146, and Gram-positive bacteriaStaphylococcus aureusATCC 25923,S. aureusATCC 43300 and yeastCandida albicansATCC 24433 strongly depended on the copper content. In addition to excellent antimicrobial activity, controlled release of Cu2+-ions from the fabrics into physiological saline solution was obtained.
