Development of Nylon/Fe3O4 Nanocomposite Triboelectric Nanogenerators for Self‐Powered Transmission Line Monitoring Applications

This study explores how the performance of triboelectric nanogenerators can be enhanced by incorporating Fe 3 O 4 nanoparticles into nylon films using a spray coating technique. Five triboelectric nanogenerator prototypes were created: one with regular nylon and four with nylon/Fe 3 O 4 nanocomposites featuring varying nanoparticle densities. The electrical output, measured by open‐circuit voltage and short‐circuit current, showed significant improvements in the nanocomposite‐based triboelectric nanogenerators compared to the nylon‐only triboelectric nanogenerator. When a weak magnetic field was applied during nanocomposite preparation, the maximum voltage and current reached 56.3 V and 4.62 μA, respectively. Further analysis revealed that the magnetic field during the drying process aligned the magnetic domains, boosting output efficiency. These findings demonstrate the potential of Fe 3 O 4 nanoparticles to enhance electrostatic and magnetic interactions in triboelectric nanogenerators, leading to improved energy‐harvesting performance. This approach presents a promising strategy for developing high‐performance triboelectric nanogenerators for sustainable energy and sensor applications.
