Optical, crystallographic, mechanical and micromorphological characteristic of AgNF. a A photograph of as-prepared fiber film after different spinning times (from left: 1, 2, 5, 10, and 20 min). b Correlation of technological parameter include transmittance and fiber thickness versus spinning time of blow-spinning. c Diameter of AgNF versus needle type. Corresponding inner diameter: 0.06 mm (G34), 0.11 mm (G32), 0.16 mm (G30), 0.21 mm (G27), and 0.26 mm (G25). d SEM of AgNF with different PVP concentration spun with G30 needle. Scale bar: 1 μm. e, f SEM images of AgNF and junction interconnected AgNF. Scale bar: 1 μm
