Fig. 1

a A modified blow-spinning system with environmental control accessories, including temperature controlled compressed air regulator and fiber collector. b Photograph of as-prepared RAPSF with silver metallic luster. c Schematic diagram of the blow-spinning and phase separation processes. d Photograph of jet flow at the needle tip during blow spinning, captured by a high-speed camera. e False-color SEM image of a single RAPSF (f) and its zoom-in image. g Cross-sectional SEM image of RAPSF, evidencing the porous structure within the polymer skeleton. h XRD spectra of as-prepared RAPSF and reference pattern (JCPDS file no. 04-0783, silver). i XPS spectrum differentiation imitating analysis of the Ag3d peak of RAPSF. j BET results for RAPSF and SF.
