Layer-by-layer approach to engineer and control conductivity of atmospheric pressure vapor phase polymerized PEDOT thin films

Smart textiles for human–machine interface fabricated via a facile on-site vapor-phase polymerization

“…The bands between 1400 and 1500 cm À1 originated from the C a = C b (-O) symmetric stretching vibration in the PEDOT neutral structure chains. 47,48 A number of significant changes were revealed in this series of spectra with the addition of PEG increasing. The most significant one was a shift in the symmetric C a = C b (ÀO) stretch band, which moved from 1429 cm À1 in 0-PEDOT to 1434 cm À1 in 12-PEDOT (Fig.…”

A two-dimensional conductive polymer/V2O5 composite with rapid zinc-ion storage kinetics for high-power aqueous zinc-ion batteries

“…53 For the composite sample, a series of additional peaks in the range from 1100 to 1600 cm −1 can be observed, in which the peaks at 1533, 1406, and 1335 cm −1 are indexed to the stretching and bending modes of CvC and C-C in the thiophene ring, respectively, and the peaks at 1210, 1135, and 1102 cm −1 can be attributed to the C-O-C stretching mode. 54 In addition, the characteristic absorption peak of the H 2 O molecule bending vibration (1628 cm −1 ) appears as a red shift relative to that of the pristine sample, indicating a strong hydrogen bond interaction between H 2 O molecules and PEDOT. The morphology and chemical composition of the PEDOT/V 2 O 5 composite were further investigated by scanning electron microscopy (SEM) and transmission electron microscopy (TEM).…”
