Morphological and permeable properties of antibacterial double-layered composite nonwovens consisting of microfibers and nanofibers

Antimicrobial activity of silver nanoparticles encapsulated in poly-<em>N</em>-isopropylacrylamide-based polymeric nanoparticles

“…For example, the antimicrobial activity of Ag-impregnated nylon fibers against Staphylococcus aureus and Candida albicans was evaluated for wound dressing. 13,14 AgNPs have also been used to treat Escherichia coli because of their ability to damage bacterial cell walls. 15 Currently, AgNPs in burn ointments, wound dressings, and Ag-coated medical devices such as catheters, vascular grafts, and endotracheal tubes are used to prevent and treat bacterial infections.…”

Removal of oil from water using magnetic bicomponent composite nanofibers fabricated by electrospinning

“…Solid or internally-porous fibers, or smooth or rough fiber surface can be obtained by just a simple manipulation of several parameters. Composite mats can also be fabricated by incorporating nanoparticles through simple blending with the polymer solution to provide additional functionalities [24], or the combination of different polymeric nanofibers into one hybrid mat through multi-nozzle electrospinning [25]. Multi-nozzle electrospinning combines the properties of different polymers to provide a synergistic property effect on the hybrid mat [26].…”

Antibacterial thermoplastic polyurethane electrospun fiber mats prepared by 3-aminopropyltriethoxysilane-assisted adsorption of Ag nanoparticles

“…In some of the applications such as antibacterial filtration and wound dressing, antibacterial activity is necessary. However, neat TPU electrospun mats do not have intrinsic antibacterial properties [17] and hence, antibacterial function is usually introduced by incorporation of an antibacterial agent such as ionic liquid and AgCl nanoparticles into the electrospinning solution or after electrospinning [18,19] . For example, Xing et al [18] obtained multifunctional TPU electrospun mats by co-electrospinning TPU with a small amount of ionic liquid (IL), and the as-spun TPU/IL fiber mats have excellent antibacterial properties owing to the quaternary ammonium structure of the IL.…”

“…For example, Xing et al [18] obtained multifunctional TPU electrospun mats by co-electrospinning TPU with a small amount of ionic liquid (IL), and the as-spun TPU/IL fiber mats have excellent antibacterial properties owing to the quaternary ammonium structure of the IL. Kang et al [19] reported that the TPU/AgCl composite fiber mat obtained by co-electrospinning TPU and AgCl nanoparticles can significantly improve the antibacterial properties of the TPU melt-blown nonwovens.…”

“…Another merit brought by APS is the improved hydrophilicity of the mat, facilitating the applications of Ag NP-decorated TPU mats in fields dealing with aqueous medium or moisture such as biomedical field and aqueous filtration. Compared with the existing methods for the preparation of antibacterial TPU fiber mats [18,19] , the application situation of the current mats is different from that of TPU/IL fiber mats which are only effective under alkaline pH conditions because of their cationic surface activity [34] , and the existence of Ag NPs only on the fiber surfaces in the current case can facilitate more efficient use of the antibacterial function of Ag NPs than the homogeneous incorporation of AgCl nanoparticles in the case of TPU/AgCl co-electrospun fibers [19] . Although the TPU fiber mats prepared by the existing methods have good antibacterial properties [18,19] , the method reported in this work is complementary to the existing methods for preparing antibacterial TPU fiber mats.…”
