Exploration of Ultralight Nanofiber Aerogels as Particle Filters: Capacity and Efficiency 2021-03-31

The potential of ultra-light nanofiber aerogels (NFA) and nanofiber sponges for particle or aerosol filtration has been studied. These two characteristics are in sharp contrast, the pressure drop of the latter increases significantly with the increase of filtration time, and the sensitivity to high frequency operating speed is increased by 105 times.

Electrospun Antimicrobial PVDF-DTAB Nanofibrous Membrane for Air Filtration: Effect of DTAB on Structure, Morphology, Adhesion, and Antibacterial Properties 2021-03-31

This article reports that the DTAB modified membrane exhibits antibacterial properties against Staphylococcus aureus subspecies. A concentration of 0.5% by weight of DTAB in the spinning solution will only partially inhibit bacterial growth, while a concentration of 1.0% by weight will result in complete inhibition of bacterial growth.

Preparation and characterization of tree-like cellulose nanofiber membranes via the electrospinning method 2021-03-31

The air filtration efficiency of the cellulose acetate dendritic nanofiber membrane can reach 99.58%, and the final cellulose dendritic membrane still maintains 98.37%. The small average pore size caused by the dendritic structure and the strong resistance to organic solvents make it a potential candidate for membrane separation.

Preparation and characterization of electrospun polyacrylonitrile fiber mats containing Garcinia mangostana 2021-03-31

As the mango contained in the spinning solution increases, the amount of mango released from the sample increases proportionally. This research proves the potential of developing electrospun fiber membranes with antibacterial and anti-tuberculosis properties, which is beneficial for filtration applications in respirators, masks and air-conditioning filters.

Electrospun soy-protein-based nanofibrous membranes for effective antimicrobial air filtration 2021-03-31

In this study, a multifunctional and antibacterial nanofiber membrane was prepared. The antibacterial properties of nanofiber membranes against Escherichia coli and Bacillus subtilis were studied. The successful synthesis of SPI/PA6-AgNPs nanofiber membrane will make it a potential candidate for a new type of antibacterial and high-performance air filter.

Depth filtration of airborne agglomerates using electrospun bio-based polylactide membranes 2021-03-31

In order to study the filtration performance of electrospun bio-based polylactic acid air filter membrane, we used gravimetric analysis to determine the permeability of three kinds of dust particles in different fiber filter membranes. The results show that it can effectively capture deeper penetrating particles, but these particles will not be captured by the electrospun air filter membrane.

Electrospun waterproof breathable membrane with a high level of aerosol filtration 2021-03-31

By changing different parameters (polymer concentration, voltage, feed flow rate, etc.), several nanofiber polyurethane (PU) fiber webs were electrospinned (ES). The results show that the ES membrane we selected shows a very efficient aerosol filtration effect, can completely remove particles larger than 0.5 microns, and the concentration of smaller particles is reduced by 94%.

Polylactic acid-glycolic acid nanofiber membrane capable of efficiently capturing nano/micron particles 2021-03-31

Particles smaller than 2.5 microns can easily enter the human respiratory system. Therefore, we have developed a purification material. It is much more efficient than a typical commercial fiber filter and has a much lower pressure. These features, coupled with the availability and biocompatibility of materials, have immeasurable potential in the development of air purifiers..

How it Fabricate Bio-Based Air Filters with Advanced Performance 2021-03-12

The research group to create an effective multifunctional biological air filter having antibacterial and filtration properties by combining nanotechnology and biotechnology techniques. AgNPs introduced imparts zNFs-Ag @ PT filter potent antimicrobial activity and provide anisotropy field as a substrate, and are arranged to achieve tensile finer than the free form of AgNPs nanofibers fibers.

Electrospun SF/PVA Nanofiber Filters for Highly Efficient PM2.5 Capture 2021-03-26

PVA is commonly used in the manufacture of continuous nanofibers. Under the same pressure drop of 50 Pa, the PM2.5 removal efficiency of the SF/PVA filter is 99.11 +/- 0.24%, which is about 10% higher than that of the pure PVA filter. SF/PVA nanofiber air filter has excellent filtering performance and has broad prospects in preventing PM pollution.
