| Abstract [eng] |
This study presents the research and development of filtration layers utilizing functionalized nanofibers, demonstrating enhanced barrier performance and functionality in comparison to traditional nonwoven layers used in Medical Devices (Medical face masks). The fabrication involved electrospinning techniques to produce functionalized nanofibers, utilizing sustainable polymers to mitigate environmental impact. These polymers were functionalized with photoactive and organic materials to tailor specific properties. Pre-electrospinning, rheological properties of polymer solutions were analyzed, while post-electrospinning focused on the morphological (SEM) and chemical composition of the nanofibers (EDX, FTIR). Given the intended medical application, antibacterial efficacy of the functionalized nanofibers was evaluated. Additionally, the barrier performance (Particle Filtration Efficiency, Differential pressure) of the electrospun layers were investigated, revealing advantages over conventional nonwoven sheets in terms of cost-effectiveness and functionality. |
