Abstract

Polypropylene non-woven fabrics (PNWs) are widely utilized in sectors such as healthcare and filtration due to their favorable properties, including low density, chemical resistance, and cost-effectiveness. However, their use in personal protective equipment (PPE), particularly during the COVID-19 pandemic, highlighted limitations such as the risk of viral adherence and secondary transmission, as well as concerns regarding single-use waste management. This study presents a method for developing durable antiviral PNWs by covalently grafting Polyquaternium-11 (PQ), a biocompatible cationic polymer, onto PNW surfaces using tri(ethylene glycol)di(azidoformate) as a crosslinker through photolytic C-H insertion at ambient temperature. The process was confirmed via FT-IR, while thermal, crystallinity, and tensile characterization indicated stable integration of PQ without compromising the mechanical properties of the PNW. The modified PNW exhibited significant antiviral and antibacterial performance, achieving 98.97% virus inactivation and 99.20% inhibition of S. aureus. This study demonstrates an effective approach for creating antimicrobial PNWs with potential applications in medical, hygiene, and PPE products.

期刊介绍： Reactive & Functional Polymers provides a forum to disseminate original ideas, concepts and developments in the science and technology of polymers with functional groups, which impart specific chemical reactivity or physical, chemical, structural, biological, and pharmacological functionality. The scope covers organic polymers, acting for instance as reagents, catalysts, templates, ion-exchangers, selective sorbents, chelating or antimicrobial agents, drug carriers, sensors, membranes, and hydrogels. This also includes reactive cross-linkable prepolymers and high-performance thermosetting polymers, natural or degradable polymers, conducting polymers, and porous polymers. Original research articles must contain thorough molecular and material characterization data on synthesis of the above polymers in combination with their applications. Applications include but are not limited to catalysis, water or effluent treatment, separations and recovery, electronics and information storage, energy conversion, encapsulation, or adhesion.
