Trioxide WO3 peak at 805 cm-1 along with the 933 cm-1 peak identified as radical cations are located at the similar position. The strong peak of C=C stretching is shifted to 1568 cm-1 , revealing that reduced doping level and thus significantly less conductive PPy composites [35] are obtained. The 1328 cm-1 peak (C-C stretching) was detected only in PPy/DBS-EG, though PPyPT and PPyCDC showed an additional broad peak at 1350 cm-1 that belongs towards the ring stretching mode on the polymer backbone [36] overlapping the CDC signals of the D peak (Figure 2a). The double peaks of the C-H in plane deformation (oxidized amount of PPy [35]) did shift at the same time to 974 and 1044 cm-1 with ratios found for PPy/DBS-EG at 0.63, PPyPT-EG at 0.8 and PPyCDC-EG at 0.87 having substantially reduced Ethyl Vanillate Autophagy polaron content material in comparison to PPyDBS, PPyPT and PPyCDC samples. The polaron content material is associated with the conductivity [37], agreeing nicely with all the five times reduced conductivity of PPy composites produced in EG (Table 1). The EG peaks have been not identified in Raman resulting from sturdy PPy peaks overlapping these peaks.PF-06873600 MedChemExpress Materials 2021, 14, x FOR PEER Overview Materials 2021, 14,7 of 19 7 ofFigure 2.
