Copper oxide nanoparticles (CuO-NPs) coated cotton, starched cotton and their functionalized CuO-Ag nanocomposites and Cu(II) curcumin complex coated cotton have been prepared. The use of starched cotton materials instead of pristine cotton is to minimize the leaching of CuO-NPs. The use of none-toxic biocompatible starch has improved the adhesion properties of the cotton fibers and enhanced its durability towards CuO-NPs. The antimicrobial activities of these coated cotton materials have been examined. The results have showed excellent antimicrobial activity against E. coli and S. aureus for all coated materials. Since that these materials have strong antimicrobial activity therefore, they could also have excellent antiviral activity and can be used to combat the spread of COVID-19 Corona Virus and attempts for minimizing corona virus outbreak. The use of textile fabrics in health facilities such as medical cloths for doctors, nurses, cleaning personnel and patients, could contribu...

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/Cu 2 O nanoparticles (NPs) on the fabric surface in the second step. The in situ synthesis of the CuO/Cu 2 O NPs was based on the adsorption of Cu 2+-ions by the introduced amino groups of the sol-gel coating. The adsorbed Cu 2+-ions are subsequently reduced in the alkaline solution of NaBH 4. X-ray diffraction measurements confirmed the formation of CuO/Cu 2 O 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-negative Escherichia coli ATCC 25922, E. coli ATCC BAA 2469, and Klebsiella pneumoniae ATCC BAA 2146, and Gram-positive bacteria Staphylococcus aureus ATCC 25923, S. aureus ATCC 43300 and yeast Candida albicans ATCC 24433 strongly depended on the copper content. In addition to excellent antimicrobial activity, controlled release of Cu 2+-ions from the fabrics into physiological saline solution was obtained.

Cu2O, CuO, ZnO-microparticles with different size and morphology directly influences their antimicrobial potential. In this study, the possible improvement of the antibacterial and washing resistance up to 20 washing cycles performance of 100% cotton fabrics were investigated. At high temperatures, carboxylic acids form ester-type crosslinking with cellulose molecules and provide antibacterial activity. For this purpose, carboxylic acids such as BTCA and CA were used in this study.The purpose of this research was to evaluate 1,2,3,4-butantetracarboxylic acid (BTCA) and citric acid monohydrate (CA) as an crosslinking agent for washing resistance of 100% cotton textile substrates against, Staphylococcus aureus (ATCC 43300), Bacillus subtilis (NRRL NRS-744), Escherichia coli (ATCC 35218) and Klebsiella pneumoniae (ATCC 70063). Cupper oxide and zinc oxide were assimilated in the coating bath for the antibacterial property. BTCA concentration in the solutions influenced the antibacterial and washing properties of the cotton fabrics. The Fourier Transform Infra-Red-Attenuated Total Reflection (FTIR-ATR) spectra showed a new summit that confirmed the ester linkage formation and crosslinking reaction for application.
TiO2/Cu Composite NPs Coated Polyester Fabric for the Enhancement of Antibacterial Durability
IOP Conference Series: Materials Science and Engineering
Copper nanoparticles (Cu NPs) were synthesized on a plasma treated polyester fabric having a coating of TiO2 NPs. The fabric was treated with cold O2 plasma first to enhance the surface affinity for TiO2 NPs, then coated with TiO2 NPs via a heat pressing, and finally synthesize Cu NPs on the complex surface using a dip-coating process. The resulting fabric shows an excellent antibacterial effect and outstanding laundering durability, as it has satisfactory bacterial reduction performance against S. aureus and E. coli higher than 98% and behaves stable even after 50 washing cycles. This methodology for preparing antibacterial polyester fabric maybe of high potential applications in cosmetic and medical textiles.

Textile materials with fluorescent, repellent, or antimicrobial properties are increasingly used in common applications. Obtaining multi-functional coatings is of wide interest, especially for applications related to signaling or to the medical field. In order to increase the performance (color properties, fluorescence lifetime, self-cleaning or antimicrobial properties) of textile materials with special uses, a series of research was carried out regarding the modification of surfaces with nanosols. In this study, coatings with multiple properties were obtained by depositing nanosols on cotton fabrics generated through sol–gel reactions. These multifunctional coatings are hybrid materials in which the host matrix is generated using tetraethylorthosilicate (TEOS) and network modifying organosilanes:dimethoxydimethylsilane (DMDMS) or dimethoxydiphenylsilane (DMDPS) in a 1:1 mass ratio. Two curcumin derivatives were embedded in siloxane matrices, a yellow one (CY) that is identical to ...

The efficacy of surfactants in stabilizing CuO-NPs onto the surface of the cotton fibers and their ability to produce homogeneous CuO-coated cotton composite was studied using different types of surfactants. The use of surfactants provides better adhesion of the CuO NPs and consequence, enhanced its coating stability during exploitation. The optical structure and morphology of the coated cotton fabrics were examined by several methods include: X-ray diffraction (XRD), scanning electron microscope (SEM), X-ray photoelectron spectroscopy (XPS) and Fourier transform spectroscopy (FTIR). The CuO-NPs-coated cotton fabrics have resisted the intensive 10 washing cycles in particular, in presence of SDS (25% loss of CuO) in comparison with TX-100 (66.5% loss of CuO). The CuO-NPs coated cotton materials have also showed an excellent inhibition for the growth of the medically relevant staphylococcus aureus and escherichia coli respectively by 91% and 95% using SDS and HY.
Antibacterial Bio-Nanocomposite Textile Material Produced from Natural Resources
Nanomaterials
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 th...
