Self-Powering Gas Sensing System Enabled by Double-Layer Triboelectric Nanogenerators Based on Poly(2-vinylpyridine)@BaTiO₃ Core–Shell Hybrids with Superior Dispersibility and Uniformity

ACS Nano, Journal Year: 2024, Volume and Issue: 18(19), P. 12146 - 12157

Published: April 30, 2024

Current core-shell hybrids used in diverse energy-related applications possess limited dispersibility and film uniformity that govern their overall performances. Herein, we showcase superdispersible (P2VP@BaTiO3) composed of a poly(2-vinylpyridine) (P2VP) (5-20 wt %) barium titanate oxide (BaTiO3), maximizing dielectric constants by forming the high-quality uniform films. The P2VP@BaTiO3-based triboelectric nanogenerators (TENGs), especially 10 % P2VP (P2VP10@BaTiO3)-based one, deliver significantly enhanced output performances compared to physically mixed P2VP/BaTiO3 counterparts. P2VP10@BaTiO3-based double-layer TENG exhibits not only an excellent transferred charge density 281.7 μC m-2 with power 27.2 W but also extraordinary device stability (∼100% sustainability maximum voltage for 54,000 cycles ∼68.7% retention even at 99% humidity). Notably, introducing MoS2/SiO2/Ni-mesh layer into this enables ultrahigh up 1228 m-2, which is top value reported TENGs so far. Furthermore, demonstrate near-field communication-based sensing system monitoring CO2 gas using our developed self-powered generator performance robustness.
