Preparation of Antibacterial Cellulose Fabric via Copper (II) Oxide and Corn Silk (Stigma maydis) Nanocomposite

Abstract

Concerning the increasing demand for antibacterial nature-based textiles, this work deals with the modification of cotton fabric with corn silk as a natural polymer together with the in situ synthesis of copper (II) oxide nanoparticles.Copper acetate is used as a precursor of copper (II) oxide and ascorbic acid as an environmentally friendly reducing agent. The copper (II) oxide/corn silk nanocomposite cotton fabrics are evaluated by FESEM, XRD, FTIR, water absorption, and antibacterial analysis. The treated fabrics exhibit higher water absorption and FESEM images along with EDX spectra confirm the formation of copper (II) oxide nanoparticles and corn silk layer on the fabric surface. FTIR analysis also establishes effective assembling of CuO/corn silk on the cotton surface. Moreover, the antimicrobial efficiency of the nanocomposite is verified to be higher than 90% against Gram-negative and Gram-positive model bacteria comprising Escherichia coli and Staphylococcus aureus, and antifungal properties against Candida albican. Consequently, the fabrication of copper (II) oxide/corn silk nanocomposites on the cotton fabric could be potentially applied for the preparation of antibacterial medical textiles.

“…In this way, the functionality and properties of the textile enhance and also the accessibility and efficiency of the nanoparticles improve. [15] Zinc tin oxide which is also known as zinc stannate is a very interesting metal oxide, that is, considered as a semiconductor with high electron mobility. [16,17] It has found many applications in the electronic and optical field and environmental fields.…”

Utilization of Polyacrylonitrile Waste Fibers in Metal-Organic Framework Matrix for Forming Bioactive Composites Film

“…66, No. 9 (2023) comparison to natural antibacterial agents, these substances have low poisonousness, adjustment synthetic substances, and warm obstruction [13][14][15]. The preference for copper nanoparticles linked to silver is due to the minor expense of copper over silver, the physical and synthetic dependability, and the simplicity of blending in with polymers.…”

“…More modest nanoparticles offer higher action but may bring about bunch development and cause a reduction in fundamental properties [15].Researchers have focused their attention on cellulose fibers (cfs) throughout the last decade. Cfs are hydrophilic, have high porosity and sweat-absorbing characteristics, are affordable, renewable, biodegradable, and flexible, and are frequently utilized [6].In addition, metal surfaces, such as copper, are well-known for their antibacterial properties, as Cu ions have been shown to inhibit bacterial growth [7][8][9][10][11][12][13][14].The presence of copper species and a stable pillar are expected to have a synergistic impact, increasing the antibacterial activity of the modified surface. By combining the antibacterial properties of MOF-199 with the immobilization of these chemicals to cellulose fibers, a cellulose-MOF could provide a novel approach [6,8].…”

“…Different MOFs, including Cu-MOF, Zr-MOF, Zn-MOF, and Al-MOF, have recently been applied [15][16][17][18][19][20]. MOFs have been examined to take a gander at their applications like gas stockpiling, gas partitioning of harmful substances, heterogeneous catalysis, energy production, detection, drug conveyance, gadgets, bioreactors, optics, catalysts, the capacity of clean energies, environmental and biological applications [12][13][14]Many researchers are intrigued by the use of MOFs in wastewater treatment. Metal-organic framework materials (MOFs) are two-or threedimensional structures made up of metallic ions and bridging organic linkers employed in various applications such as the elimination of microorganisms and hazardous organic compounds.…”
