Electrospun amine-functionalized silica nanoparticles–cellulose acetate nanofiber membranes for effective removal of hardness and heavy metals (As(v), Cd(ii),Pb(ii)) in drinking water sources

Abstract

Due to growing urbanisation and rising population, the world is approaching a point where there will be insufficient clean water for human consumption. There are still a significant number of...

Preparation and characterization of Fe–ZnO cellulose-based nanofiber mats with self-sterilizing photocatalytic activity to enhance antibacterial applications under visible light

“…Then an aluminium foil was spread on the ground collector to collect fibers. The solution was electrospinning using 16 kV voltage, a 13 cm tip to collector distance, and a 1.5 mL h −1 flow rate to produce the CA nanofiber mat, ZnO nanoparticles incorporated the CA mat and Fe 5%–ZnO nanohybrid incorporated the CA nanofiber mat 52 using SKE EF100 electrospinning system with a static collector plate at ambient room temperature and humidity.…”

The antimicrobial synergy of polymer based nanofiber mats reinforced with antioxidants intercalated layered double hydroxides as a potential active packaging material

“…Aluminium foil was spread on the collector plate. The process was started after setting the electrospinning parameters and continued for about 4 h. The electrospinning parameters were; voltage of 16 kV, flow rate of 1.5 ml h −1 , distance between the spinneret and the collector of 13 cm, temperature of 30 °C and humidity of 78% [39]. Then acetone and DMF were mixed in a 2:1 V/V ratio, such that 4 ml of acetone and 2 ml of DMF.…”

Visible‐Light‐Active Electrospun Membranes Based on Cobalt‐Doped ZnO Nanohybrids: Applications for Food Packaging

“…Electrospun nanofiber (NF) membranes have recently piqued the interest of researchers in a variety of fields, including catalysis, medicine, sensing, and energy due to their small diameter, high porosity, large surface area‐to‐volume ratios, controllable morphology, tunable network geometry, high chemical and thermal stability, good internal connectivity, and high mass transport properties, among others [1,2] . The electrospinning process is extensively used to manufacture nanofiber mats because it is a unique, simple, and effective solution‐based method that simplifies mass production, resulting in a high yield of nanofibers with stable and robust connection and good mass transfer capabilities, among other benefits [3,4] …”

“…Co‐ZnO nanoparticles are incorporated into polymeric nanofiber mats, employing an electrospinning technique, controlling several parameters such as solution, processing, and ambient parameters. Advantages of the electrospinning method include high efficiency and surface area, diameter control, structural adjustment, superior nanofiber characteristics, and robust scaling [4,24,25] . For the electrospinning process, a biopolymer is used to prepare nanofiber membranes and cellulose acetate was utilized since it is a biodegradable and biocompatible polymer with cost‐effectiveness, high affinity, high surface area, high porosity, lightweight and adhesion properties, among other things [26] …”
