A) Transmittance of non- (▽), MeOH- (○), and MeOH-GTA-treated (◊)SELP-47 Kdry films of 30 μm thickness. Measurements were done in triplicate. Insert: photo images of SELP- 47 K films cast on coverslips [131]., B) FESEM images of nanoribbons obtained by electrospinning from aqueous solution at various concentrations of SELP47K 6% (a), 9% (b), 12% (c), 15%(d), 18% (e) (w/w) and low magnification image at 15% (f), other electrospinning conditions were kept at a constant applied voltage (20 KV), collecting distance (15 cm) and flow rate (0.1 mL/h). (Scale bar – a–e: 1 μm, f: 25 μm) [134]. Figures were reproduced with permission from the cited articles.
