  • a controlled design of ripple like polyamide 6 nanofiber nets membrane for high efficiency Air Filter
    Small, 2017
    Co-Authors: Shichao Zhang, Jianyong Yu, Bin Ding

    Abstract:

    The filtration capacity of fibrous media for Airborne particles is restricted by their thick diameter, low porosity, and limited frontal area. The ability to solve this problem would have broad technological implications for various Air filtration applications; despite many past efforts, it remains a great challenge to achieve. Herein, a facile and scalable strategy to fabricate the ripple-like polyamide-6 nanofiber/nets (PA-6 NF/N) Air Filter via combining electrospinning/netting technique with receiving substrate design is demonstrated. This proposed approach allows the scaffold filaments to orderly embed into 2D PA-6 nanonets layer with Steiner-tree structures and nanoscale diameter of ≈20 nm, resulting in the ripple-like membrane with extremely small pore size, highly porous structure, and hugely extended frontal surface, by facilely adjusting its pleat span and pleat pitch. These unique structural advantages enable the ripple-like PA-6 NF/N Filter to filtrate the ultrafine particles with high removal efficiency of 99.996%, low Air resistance of 95 Pa, and robust quality factor of >0.11 Pa−1; using its superlight weight of 0.9 g m−2 and physical sieving manner. This approach has the potentialities to give rise to a novel generation of Filter media displaying enhanced filtration capacity for various applications thanks to their nanoscale features and designed macrostructures.

  • Cleanable Air Filter Transferring Moisture and Effectively Capturing PM2.5
    Small, 2017
    Co-Authors: Xinglei Zhao, Jianyong Yu, Yuyao Li, Pan Jiang, Bin Ding

    Abstract:

    The lethal danger of particulate matter (PM) pollution on health leads to the development of challenging individual protection materials that should ideally exhibit a high PM2.5 purification efficiency, low Air resistance, an important moisture-vapor transmission rate (MVTR), and an easy-to-clean property. Herein, a cleanable Air Filter able to rapidly transfer moisture and efficiently capture PM2.5 is designed by electrospinning superhydrophilic polyacrylonitrile/silicon-dioxide fibers as the adsorption–desorption vector for moisture-vapor, and hydrophobic polyvinylidene fluoride fibers as the repellent components to avoid the formation of capillary water under high humidity. The desorption rate of water molecules increases from 10 to 18 mg min−1, while the diameters of polyacrylonitrile fibers reduce from 1.02 to 0.14 µm. Significantly, by introducing the hydroxyl on the surface of polyacrylonitrile nanofibers, rapid adsorption–desorption of the water molecules is observed. Moreover, by constructing a hydrophobic to super-hydrophilic gradient structure, the MVTR increases from 10 346 to 14 066 g m−2 d−1. Interestingly, the prepared fibrous membranes is easy to clean. More importantly, benefiting from enhanced slip effect, the resultant fibrous membranes presented a low Air resistance of 86 Pa. A field test in Shanghai shows that the Air Filter maintains stable PM2.5 purification efficiency of 99.99% at high MVTR during haze event.
