Electrospun Polyamide6 Chitosan Nanofibers Reinforced with Zinc Oxide Nanoparticles and Functionalized MultiWalled Carbon Nanotubes: Some Physical, Mechanical Properties and Bacterial Rejection

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.
