The removal efficiency of traditional air filters decreases with decreasing particle size. To tackle this issue, this study proposes a novel approach by combining triboelectric nanogenerator (TENG) properties with air filters and face masks. The study investigates key parameters such as airflow velocity, particle size, and applied voltage, and suggests suitable triboelectric materials. Results show that the suggested triboelectric-based filter improves the removal efficiency from 23.0% to 99.0%, with a 4 times higher efficiency compared to traditional filters. The study highlights the potential of utilizing antibacterial and polymer-based triboelectric materials in various applications.
The removal efficiency of traditional air filters decreases with decreasing particle size, requiring the use of highly compact filter layers to achieve high efficiency, resulting in high-pressure drops and power consumption. To address this issue, this study proposes a novel approach by combining triboelectric nanogenerator (TENG) properties with industrial air filters and face masks to improve removal efficiency while maintaining low-pressure drop. The study investigates the impacts of key parameters, such as airflow velocity, particle size, and applied voltage, on filter performance through a developed mathematical model. The optimal voltage range required to remove specific particle sizes is also modeled, and suitable triboelectric materials for producing the optimal voltage are suggested. Results show that the use of the suggested triboelectric-based filter, generated using a polypropylene (PP)-polyurethane (PU) TENG pair, with a 300 mu m filter thickness, 30 mu m pore size, and 30 mu m fiber diameter, enhances the removal efficiency of particles from 23.0 % to 99.0 %. Specifically, a 10 V voltage on the fiber surface enables the removal of particles in the range of 10 nm to 100 mu m with an efficiency of 99.0 %, which is 4 times higher than a traditional filter. The study demonstrates the potential of utilizing various antibacterial and polymer-based triboelectric materials in different applications, including self-powered smart face masks and industrial air filters.
