From: Ultrathin, ultralight dual-scale fibrous networks with high-infrared transmittance for high-performance, comfortable and sustainable PM0.3 filter

Fig. 2

a Diagram and optical image of the formation of dual-scale fibers. b Properties of 5.5 wt% PA6 solutions doped with various DTAC contents. SEM images of (c) PA6, d PA6/DTAC-1, e PA6/DTAC-2, f PA6/DTAC-3, g PA6/DTAC-4 fiber filters. Diameter distribution of (h) 5.5 wt% PA6 fibers and (i) dual-scale fibers. j Fiber diameter comparison of this work and other spinning techniques. Error bars represent the standard deviation of the measured properties and the samples are at least three. Source data are provided as a Source Data file.
