Abstract: Nanofibrous membranes have shown great potential in air filtration; however, studies on charge regulation strategies remain relatively limited. In this work, PVDF/PA66 nanofibrous membranes with different pore sizes were fabricated via electrostatically assisted solution blow spinning (E-SBS). A controllable vibration treatment was introduced to regulate the charge amount of the membranes, enabling a systematic investigation of the synergistic effects of pore size and charge on filtration performance. The results indicate that pore size plays a crucial role in determining filtration performance: as the average pore size increases from 8 μm to 16 μm, the filtration efficiency decreases from 99.26% to 95.98%, while the pressure drop is significantly reduced. The quality factor reaches a maximum value of 0.0391 Pa⁻¹ at a pore size of 14 μm, demonstrating an optimal balance between efficiency and resistance. With the introduction of vibration treatment, the charge amount is significantly enhanced to 3742.83 pC at an optimal vibration condition (1800 cycles), resulting in an improved filtration efficiency of 99.89%, a reduced pressure drop of 84.7 Pa, and an increased quality factor of 0.0803 Pa⁻¹, which are markedly superior to those of the untreated samples. The enhanced filtration performance is attributed to the synergistic effect of pore structure and charge characteristics, where an appropriate pore size provides effective physical interception, while sufficient charge enhances electrostatic capture.
