Abstract
Triboelectric nanogenerators (TENGs) provide an effective method for harvesting mechanical energy and converting it into electrical power. Polydimethylsiloxane (PDMS)-based TENGs are particularly advantageous due to their excellent mechanical properties, high flexibility, simple manufacturing process, and low cost. In this study, we suggest a PDMS-based TENG by integrating surface-modified carbon nanotubes (SMCs) prepared by pulsed laser ablation (PLA), along with high-permittivity BaTiO3 (BTO) nanoparticles. The combination of SMCs' superior electrical conductivity and BTO's high dielectric constant has synergistically enhanced the TENG's performance. Compared to pristine PDMS-based TENGs, the TENG incorporating 0.05 wt% SMCs and 7 wt% BTO demonstrated a remarkable 200 % increase in voltage (432.44 V) and a 324 % increase in current (39.23 μA). Also, plasma treatment further boosts the triboelectric performance, achieving a voltage of 468 V, a current of 43.04 μA, and a power density of 7.83 W/m².
