(a) Schematic showing the synthetic steps. (1) Flexible PAN/BA-a and SiO2 nanofibre membranes are produced by electrospinning. (2) Homogeneous nanofibre dispersions are fabricated via high-speed homogenization. (3) Uncrosslinked NFAs are prepared by freeze drying nanofibre dispersions. (4) The resultant FIBER NFAs are prepared by the crosslinking treatment. (b) An optical photograph of FIBER NFAs with diverse shapes. (c–e) Microscopic architecture of FIBER NFAs at various magnifications, showing the hierarchical cellular fibrous structure. (f) Schematic representation of the dimensions of relevant structures. Scale bars, 20 μm (c), 5 μm (d) and 1 μm (e).
