    Mussel-inspired approach to cross-linked functional 3D nanofibrous aerogels for energy-efficient filtration of ultrafine airborne particles by Zhang, Youfang, Zeng, Zhihui, Ma, Daphne Xiu Yun, Zhao, Chenyang, Ang, Jia Ming, Ng, Bing Feng, Wan, Man Pun, Wong, Shing-Chung, Wang, Zhe, Lu, Xuehong

    Published 2019
    “…Morphology characterization andcompression tests showthatboth multiplehydrogen bondingfacilitated bythePDA coating and Fe3+-PDA coordination bonding could effectively induce the formation of inter-fiber junctions, enhancing compression resistanceofthe3DNFAsandleadingtohierarchical porousstructureswithaverywidePSD.When a thin layer of the optimized 3D NFA with a large specific surface area (85.7m2g−1) is combined with a commercial air filter, the composite filter obtained exhibits high filtration efficiencies of 99.72% and 99.85% for airborne particles with sizes of<100nm and<500nm, respectively, at a low pressure drop of only 54.1Pa. The results show that the cross-linked NFAs could act as a highly efficient air filter for ultrafine particles while not increasing the overall pressure-drop significantly, which are due to the good adhesive properties of PDA, electrostatic charge induced by Fe3+, and high porosity and hierarchical porous structures of the 3D NFAs.…”
