摘要

High energy consumption and electric field nonuniformity severely limit the scalability and reproducibility of bubble electrospinning for producing morphologically consistent polymer nanofibers. To address these challenges, we presented a simulation-guided design of a high-curvature auxiliary electrode array based on a spherical arc configuration. Using COMSOL Multiphysics, the effects of key geometric parameters, including pin number, spacing, diameter, length, and tip angle, on electric field distribution were systematically investigated. The optimal setup, comprising five needles (1 mm diameter, 30 mm length, 30° tip angle, 20 mm spacing), effectively mitigated edge effects and enhanced both field strength and uniformity at the bubble interface. Guided by simulations, the optimized electrode array was implemented experimentally, yielding nanofibers with significantly smaller and more uniform diameters compared to conventional bubble electrospinning systems. This work establishes a generalizable, simulation-driven framework for rational electrode design in needleless electrospinning, where geometric alignment between electrode curvature and liquid interface enables localized field enhancement with global homogeneity, offering a scalable, energy-efficient pathway toward industrial-grade nanofiber manufacturing.
