High-Performance PM0.3 Air Filters Using Self-Polarized Electret Nanofiber/Nets 2021-03-18

An innovative in-situ electret electrospinning/netting technology can simultaneously control solution phase separation and crystal phase transition, thereby developing self-polarized polyvinylidene fluoride nanofibers with 2D network and excellent surface adhesion / Omentum. The nanofiber/mesh filter shows a combination of super-hydrophobicity, required transparency (91%) and long-term stability.

Multifunctional composite membrane based on BaTiO3@PU/PSA nanofibers for high-efficiency PM2.5 removal 2021-03-18

A new type of barium titanate@polyurethane/polysulfonamide (BaTiO3@PU/PSA) composite nanofiber membrane was manufactured, which has comprehensive performance for high-temperature filtration and powerful PM2.5 removal. The capture efficiency of fine particles is as high as 99.99%, good mechanical properties, sufficient flexibility and thermal stability, good flame retardancy and resistance to compounds.

Transparent Metallized Microfibers as Recyclable Electrostatic Air Filters with Ionization 2021-03-19

We have developed an ionization assisted electrostatic air filter composed of non-woven nanofibers. The use of air ionization to ionize particulate matter (PM) can enhance electrostatic attraction, thereby promoting effective filtration. The metallization of the fiber promotes strong electrical attraction, and thus traps PM of various sizes.

Roll-to-Roll Production of Spider Silk Nanofiber Nonwoven Meshes Using Centrifugal Electrospinning for Filtration Applications 2021-03-19

Using centrifugal electrospinning technology, a non-woven web made of recombinant spider silk protein can be produced continuously roll-to-roll. The prepared spider silk nanofiber web exhibits high filtration efficiency when the fine particles are less than 2.5 microns (PM2.5), and the pressure is reduced, so it has excellent filtration efficiency.

Hydrophobic cross-linked zein-based nanofibers with efficient air filtration and improved moisture stability 2021-03-19

Multifunctional polyvinyl alcohol-soluble protein nanofibers are prepared by electrospinning with the help of polyvinyl alcohol and then cross-linking with glutaraldehyde. In this way, the moisture resistance of the nanofibers is significantly improved, while the air filtration performance is well preserved, and the relatively weak mechanical properties of zein are also improved.

3D structure design and simulation for efficient particles capture: The influence of nanofiber diameter and distribution 2021-03-19

, Designed nanofiber filters with diameters ranging from 100 to 900 nm to examine their effects on filtration efficiency, pressure drop and quality factor (QF). The simulation results were partially verified by electrospinning cellulose acetate nanofiber filters, and new insights were provided for the filter structure design with high filtration efficiency and low pressure drop.

Influence of fiber diameter, filter thickness, and packing density on PM2.5 removal efficiency of electrospun nanofiber air filters for indoor applications 2021-03-20

Electrospinning is a general technology for manufacturing nanofiber filters with high PM2.5 removal efficiency and relatively low pressure drop. Therefore, electrospun nanofiber filters can be used in buildings to reduce indoor exposure to PM2.5 and related adverse health effects.

Electrospinning of Metal-Organic Frameworks for Energy and Environmental Applications 2021-03-20

The latest developments in metal organic frameworks (MOFs) structured into nanofibers by electrospinning are summarized, including manufacturing, post-processing by pyrolysis, characteristics, and use of the resulting MOF nanofiber frameworks. Finally, the manufacturing challenges of MOF nanofibers, its use restrictions and future development trends are proposed.
