Fig. 2. The surface and mechanical characterization of the PCL–PANI–PVDF scaffolds was done. (A) Surface characterization was done using FTIR spectroscopy. The peaks unique to the functional groups present in PCL, PVDF and PANI were identified. (B) Further surface analysis was done using XRD analysis which showed two crystalline peaks characteristic of crystalline PCL nanofibers. (C) The mechanical characterization of the scaffolds was done by measuring the stress–strain response of the scaffold under isothermal conditions. (D) The table summarizes the mechanical properties of the scaffold.
