Enhancing the Antimicrobial and UV Resistance Properties of PC Blend and Recycled Cotton Fabric through Ag/TiO₂ Nanocomposite

ACS Omega, Journal Year: 2025, Volume and Issue: unknown

Published: Feb. 18, 2025

Smart fabrics with multifunctional properties, such as antimicrobial reduction, superhydrophobicity, and UV resistance, have been highly desirable in medical textiles sportswear. In this study, we demonstrate a cost-effective approach to achieving these properties. A nanosolution of silver titanium dioxide was prepared, dip coating method used coat the polyester-cotton blend 20% recycled cotton fabric. The investigation morphologies chemical composition clarified formation Ag/TiO2 on fabric surface, average particle size nanoparticles being ∼15 ∼18 nm, respectively. amorphous surfaces exhibited excellent antibacterial reduction against Staphylococcus aureus (99.99%) Escherichia coli bacteria. Due TiO2 surfaces, coated samples water contact angles 160 ± 2 141 2° for polyester (PCBF-I, PCBF-II) 148 156 (RCBF-I, RCBF-II). All showed UV-resistant whereas (RCBF-II) highest UV-protecting excellent, moderate, good color fastness wash, rubbing, light With its promising results, simple inexpensive technique is significant interest developing novel high-performance textiles, offering solution industry.

A Facile Strategy Based on Ionic Liquids to Modulate the Antibacterial, Flame‐Retardant, and Sensing Properties of Cotton Fabrics

Advanced Functional Materials, Journal Year: 2025, Volume and Issue: unknown

Published: Feb. 19, 2025

Abstract Surface treatment of textiles causes a significant amount environmental pollution and endowing traditional fabrics with multiple functions through facile methods remains challenging. Here simple strategy is proposed involving the copolymerization methacrylic acid (MA) functionalized cotton fabric (CF) vinyl‐functionalized ionic liquid (IL). The resulting CF‐PIL (where P refers to poly) shows high bacteriostatic reduction rates (BR > 99%), excellent flame retardancy (LOI = 28.1%), together sensitivity quick responsiveness. exhibits unparalleled reliability even after 50 washing cycles. CF‐PIL‐based also captures signals from mechanical stimuli, humidity, temperature. This allows material act as sensor for physiological signal monitoring (breathing, body temperature, external stimulation), high‐temperature. Through design circuit, assembled high‐temperature fire alarm system, which can provide early warning temperatures when near or in contact flames within few seconds. While many applications may be envisaged, particular relevance are intelligent firefighting suits smart architectural textiles.

SnO₂NPs as a Nontoxic Antiviral Agent for Designing Protective Masks against Human Coronavirus Infection

ACS Applied Bio Materials, Journal Year: 2025, Volume and Issue: unknown

Published: April 9, 2025

The COVID-19 pandemic has created a need to develop protective textiles that reduce the infection of SARS-CoV-2, mainly via face masks. key issue in designing is functionalization with antiviral agents. This report presents tin oxide nanoparticles (SnO2NPs) as novel, efficient agent against human coronavirus HCoV 229E due blocking virus entry, attachment, and penetration into MRC-5 cells nontoxicity. SnO2NPs were obtained by sodium stannate hydrolysis have 3 nm diameter, cubic structure, zeta potential -28.8. applied functionalize mask made silk fibroin. Polydopamine was immobilize particles. negative enhance fabric hydrophobicity, which crucial for properties. functionalized reveals very good properties antibacterial activity Gram-positive -negative bacteria. Silk retains fibroin β-sheet nontoxic, noncorrosive skin, high thermophysiological wear comfort.The highest filtration efficiency 3-layered (60%), while breathing resistance, sufficient FFP3 mask, achieved 1-layered (maximum allowable 100 300 Pa, respectively, 30 L/min 95 inhale Pa an exhale flow rate 160 L/min). can be useful developing advanced textile materials control spread future pandemics.

Synergistic Modification of Polylactic Acid Fibrous Membranes with Improved Light-Induced Antibacterial, Mechanical, and Biodegradable Performances

ACS Applied Materials & Interfaces, Journal Year: 2025, Volume and Issue: unknown

Published: April 20, 2025

Reusable and biodegradable facemasks with enhanced antibacterial mechanical functions are considered sustainable personal protective equipment (PPE) to protect the public from future outbreaks or pandemics of infectious diseases. This study successfully employed biobased plasticizers inherently work an edible photosensitizer vitamin K3 (VK3) provide a combination desired mechanical, biodegradable, onto polylactide (PLA) fibers. These additives demonstrated good compatibility VK3 PLA, resulting in improved softness toughness accelerated enzymatic degradation modified PLA membranes. Among plasticizers, glycerol tributyrate (GT) revealed superior synergistic effect membranes by promoting type I photoreaction excited VK3, which generated more than three times hydroxyl radicals compared other under both daylight (D65) UVA irradiation, addition consistent production singlet oxygen. The dramatically increased reactive oxygen species (ROS) on leads rapid function (6-log reduction Escherichia coli within 30 min), critical performance metric for biocidal materials. findings offer new insights into development eco-friendly, multifunctional, degradable facemask materials, providing promising approach PPE.
