Fig. 1. (A) Digital photograph of the aligned morphology of the PCL–PANI–PVDF scaffold as visible to the naked eye. (B) Field emission scanning electron microscopic (FESEM) images of the PCL–PANI–PVDF scaffolds exhibiting aligned morphology and overlapping fibers. Large and small diameter fibers are interspersed having the same directionality. (C) A higher magnification image reveals the interlocked pattern of large and small diameter nanofibers and their close assembly. (D) High resolution Transmission Electron Microscopy (HR-TEM) image of PCL–PANI–PVDF after staining with osmium(viii) oxide.
