Abstract
In this study, electrospinning was performed by varying the applied voltage (12–14 kV), flow rate (0.5–0.7 µL/s), and tip-to-collector distance (TCD) (14–16 cm) to produce nanofibers (NF) of polylactic acid (PLA). The scanning electron microscopic (SEM) based analysis reveals the finest NF (ɸ144.0 ± 18.0 nm) were prepared at 14 kV (applied voltage), 0.5 µL/s (flow rate), and 16 cm TCD. The resonating frequency (Rf) (3.332 GHz) has confirmed that PLA-based NF may be used as bio-sensors because of its high flexibility in body-centric applications. The results of the crystallinity, normalized heat, and glass transition temperature (Tg) confirmed the scope of PLA-NF-based sensors in repeated thermal cycles.
