From: In-situ forming dynamic covalently crosslinked nanofibers with one-pot closed-loop recyclability
a Schematic representation of the one-pot closed-loop recycling process of DCCNF-60C; b–d FESEM images of b) original, c) 1st recycled, and d) 2nd recycled DCCNF-60C; e Average fiber diameters of original and recycled DCCNF-60C; f Recovery rate of mechanical properties after each recycling cycle of DCCNF-60C; g Schematic representation of the welding process of DCCNF-60C; h FESEM images of welded DCCNF-60C with different heating durations at 100 °C; I Stress-strain curves of the original and welded DCCNF-60C with different heating durations at 100 °C.
