Sportswear textile with nanofiber membrane inside is based on the modern nanofiber technology where the core of the membrane consists of fibers with a diameter 1000× thinner than human hair. This extremely dense "sieve" with more than 2,5 billion of pores per square centimeter works much more efficiently with vapor removal and brings better ...
Alternatively, polymer can be infiltrated into 1D, 2D, 3D preform creating high content polymer nanocomposites. [ 2 ] Polymer nanoscience is the study and application of nanoscience to polymer-nanoparticle matrices, where nanoparticles are those with at least one dimension of less than 100 nm .
A nanofiber has two external dimensions in the nanoscale, with nanotubes being hollow nanofibers and nanorods being solid nanofibers. A nanoplate/nanosheet has one external dimension in the nanoscale, [20] and if the two larger dimensions are significantly different it is called a nanoribbon. For nanofibers and nanoplates, the other dimensions ...
Nanofiltration is a membrane filtration process that uses nanometer sized pores through which particles smaller than about 1–10 nanometers pass through the membrane. Nanofiltration membranes have pore sizes of about 1–10 nanometers, smaller than those used in microfiltration and ultrafiltration, but a slightly bigger than those in reverse ...
NanoH2O Inc. commercialized a membrane in which zeolite nanoparticles were synthesized and embedded within an RO membrane to form a thin-film nanocomposite, or TFN, which has proven to be more than 50-100% more permeable compared to conventional RO membranes while maintaining the same level of salt rejection.

Most nanoporous materials can be classified as bulk materials or membranes. Activated carbon and zeolites are two examples of bulk nanoporous materials, while cell membranes can be thought of as nanoporous membranes. [2] A porous medium or a porous material is a material containing pores (voids).
Electropsun propolis nanofibrous membrane showed an antiviral effect against the SARS-CoV-2 virus, and an antibacterial effect against Staphylococcus aureus and Salmonella enterica bacteria. [73] Interestingly, electrospinning allows to fabricate nanofibers with advanced architecture [ 74 ] that can be used to promote the delivery of multiple ...
The membrane produced by this method has shown dramatic enhancements in flux and selectivity in various applications, such as sea water desalination (8,9), membrane extraction (10), water purification by the removal of volatile organics from water (11) and for micro scale membrane extraction for the analysis of water pollutants (12-14).
