“…42 The infrared absorption peaks within the range of 1300−1100 cm −1 are principally caused by the stretching vibration mode of poly(tetrafluoroethylene) F− C−F (ν CF2 ), while the bending vibration mode of poly-(tetrafluoroethylene) F−C−F (δ CF2 ) leads to the peaks in the range of 700−400 cm −1 . 43 Figure 2b compares the UV−vis-NIR absorption spectra of MoS 2 nanosheets and PTFE/MoS 2 samples (located on SiO 2 /Si substrates), showing similar absorption edges. The decrease in absorptance of PTFE/MoS 2 may be caused by the reflection of the PTFE film.…”

“…Fourier transform infrared spectroscopy (FT-IR) was executed to characterize the PTFE products before corona charging, as illustrated in Figure a, with frequencies ranging from 1400 to 400 cm –1 . The infrared absorption peaks within the range of 1300–1100 cm –1 are principally caused by the stretching vibration mode of poly(tetrafluoroethylene) F–C–F (ν CF2 ), while the bending vibration mode of poly(tetrafluoroethylene) F–C–F (δ CF2 ) leads to the peaks in the range of 700–400 cm –1 Figure b compares the UV–vis-NIR absorption spectra of MoS 2 nanosheets and PTFE/MoS 2 samples (located on SiO 2 /Si substrates), showing similar absorption edges.…”
