Figure 5: SEM images of CNT yarn at different stages of the spinning process. Stage I (a), Stage II (b), Stage III (c), and Stage IV (d), schematic of the applied heating and tension spinning (HTS) stages (e). I-denotes the position before 1st applied tension; II before 2nd tension; III before 3rd tension; IV before winding on the spool; Raman spectra of CNT yarn formed from treatment 1 and treatment 4(f).
