Abstract

This study investigates the influence of coaxial electrospinning parameters on the morphological and physicochemical properties of nanofibers composed of poly(butylene co-adipate co-terephthalate) (PBAT) and polylactic acid (PLA). The nanofibers were systematically characterized using scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FTIR), differential scanning calorimetry (DSC), and mechanical testing. The findings reveal that the PBAT/PLA nanofibers exhibit a core-shell structure with a co-continuous phase. It was observed that PBAT demonstrates limited miscibility with PLA under the specific process conditions examined. Furthermore, the feed rate of the core solution was found to have a substantial impact on the resulting fiber properties
