Abstract
This research concentrates on enhancing TENGs via nylon/TiO2 nanocomposites. The integration of TiO2 nanoparticles into nylon enhances triboelectric characteristics, promoting charge transfer during mechanical deformation. Experiments demonstrate that introducing TiO2 nanoparticles to nylon by a simple spray coating method enhances dielectric permeability, favorably impacting TENG’s performance. A TENG with nylon and polysiloxane layers initially achieved 30.36 V in open-circuit voltage and 1.82 μA in short-circuit current. The introduction of TiO2 nanoparticles significantly improved performance, reaching peak values of 41.38 V and 2.5 μA after 15 spray-coating cycles. Nonetheless, excessive TiO2 incorporation diminished TENG performance by reducing the active contact area between nylon and polysiloxane layers.
