Figure 1. Illustration of fabrication of TENGs with hybrid dopants (taking dopants silver nanoparticle and g-C3N4 powder as an example). (A) Mixing of PDMS, silver nanoparticles, and g-C3N4 powders; (B) Blade coating of the mixture; (C) Structure of TENG; (D) XRD pattern of g-C3N4 powder; (E) FTIR spectra for PDMS composites with different ratios of Ag/g-C3N4; (F) Raman spectra of a sample with 1 wt. % Ag/g-C3N4 dopant at different proportions in PDMS composite; (G) SEM of Ag/g-C3N4 PDMS composite and EDS mapping of elements. TENGs: Triboelectric nanogenerators; PDMS: polydimethylsiloxane; FTIR: fourier transform infrared spectroscopy; EDS: energy dispersive X-ray spectrometry; XRD: X-ray powder diffraction; SEM: scanning electron microscopy.
