Fig. 3. Scaffolds-water interactions. Water-drop contact angle test of (Ai) gelatin-PEDOT:PSS and (Aii and Aiii) sequence of drop absorption for PDA-coated gelatin-PEDOT:PSS. (B) PBS absorption capacity and (C–F) biodegradation behavior of scaffolds. (C and D) FE-SEM micrographs of (C) un-coated and (D) PDA coated gelatin-PEDOT:PSS scaffolds, (E) Biodegradation ratio and (F) FTIR spectra of both PDA-coated and uncoated scaffolds before and after degradation. (Differences resulted statistically significant (*p ≤ 0.05) and very statistically significant (**p < 0.01)).
