With the fast development of nanotechnology, the preparation of electrospun nanofibers received increasing interest. Because of their large specific area and superior functional abilities, electrospun nanofiber membranes play an essential role in various fields, particularly in wastewater treatment. The goal of this study is to develop bacterial rejection membranes of Polyamide6/Chitosan nanofiber membranes that have pores larger than some bacterial cell types present in wastewater. Polyamide6/ Chitosan nanofiber membranes were prepared by electrospinning technique. The fabricated filters were characterized using Field emission scanning electron microscopy (FeSEM), water contact angle assessment. The diameters of nanofibers in the range of (116.88 237.34) nm were achieved. The bacterial removal efficiency of Polyamide6/ Chitosan nanocomposites on coliform and streptococci were studied. The results showed that Polyamide6/ Chitosan/1.5% Zinc Oxide nanoparticles, and (20 25) min. of reaction time resulted in the best removal efficiency: 99 % for coliform and 99.99 % for Streptococci. The bacterial cells were entrapped and damaged after passing through the membrane, as seen by Fe SEM images. As a result, these PA6/ Chitosan nanocomposites membranes appear promising for decontamination of water.

“…In antibacterial PET fibers, the antibacterial agent used determines the preparation method and the antibacterial effect of antibacterial fibers. − According to the composition of antibacterial agents, antibacterial fibers can be divided into inorganic systems, organic systems, and natural systems. − The preparation of antibacterial PET fibers mainly includes chemical grafting modification, melt blending, electrospinning, postfinishing, and so on. Vazquez et al added nano-ZnO to recycled PET (r-PET) solution and prepared ZnO-NPs/r-PET composite fibers by electrospinning, which have good antibacterial properties against Escherichia coli and Bacillus subtilis .…”

Transmission through the respiratory tract is one of the most important ways for bacteria and viruses to infect the human body; the use of high-performance antibacterial and antiviral protective equipment is the most effective way to prevent the spread of respiratory diseases. However, at present, most personal protective equipment lacks the ability to kill pathogens. In this paper, a kind of polytetrahydropyrimidine−polyethylene terephthalate functional fiber (PET−PTHP fibers) with highly sustained antibacterial and antiviral properties was prepared. The inactivation rate of the fibers against Staphylococcus aureus and Escherichia coli was as high as 99.99%, and the antibacterial time was more than 72 h. The fibers have an obvious destructive effect on lentiviruses and can reduce the infection rate of lentiviruses in BxPC-3 cells from 25.4 to 9.7%. The cytotoxicity test, cell live/dead staining test, and cell proliferation test all confirmed that PET−PTHP fibers have no obvious cytotoxicity and good cytocompatibility. By applying the functional fibers to the inner layer of the masks, a new type of mask with adsorption, filtration, and killing properties against pathogens was prepared. The filtration efficiency of the new masks was 99.3%, and the pressure drop was 104 Pa. The new masks have excellent air permeability and filtration effect, meet the practical application conditions, and are of grade A; therefore, these masks provide medical protection as well as kill pathogens at the same time, further reducing the risk of human infection.

“…It is also antimicrobial. As CS interacts with the tissue of the host, its interaction with different cellular activities related to wound healing can expedite the recovery process [ 10 , 18 ]. Thus, PCL/Chitosan combined for the coating procedure is preferable to employing than using two ingredients separately to improve biological and mechanical performance [ 19 ].…”
