a Surface SEM image of the ANF membrane (scale bar: 300 nm). The inset shows TEM image of the ANFs (scale bar: 250 nm). b Pore-size distribution of the ANF membrane obtained through data statistics of the SEM image (the gray line represents the Gauss fit). c Photograph of the cross-section view of the ANF/gel heterogeneous membrane (scale bar: 100 μm). d 2D cross-section illustration of the hybrid membrane featuring asymmetric structure and charge distribution. e Contact angle measurements of the ANF membrane and polyelectrolyte gel.
