Fig. 3. Efficient and durable triboelectric effect-enabled PM filtration. (a) Triboelectric series: comparing the charge transfer capacity of the studied materials. The dashed bars represent a qualitative ranking. (b) Triboelectric charge generation mechanism of the SAF. (c) Electrostatic potential attenuation with and without the self-charging function, indicating prolonged electrostatic adsorption capacity with self-charging. (d) Durability evaluation of filtration efficiency and pressure drop. (e) Radar chart comparing the performance of the SAF with commercial face masks.
