“…The height of the RGO sheet calculated from AFM was of 60 nm. According to Figure 9, the main Raman lines of P5A1N electrosynthesized onto the Au electrode have peaks at 738-846-939, 1193, 1276, 1322-1338, 1428, 1579 and 1620 cm -1 , these being assigned to the vibrational modes of the C-H bond, the deformation of the C-C bond in naphthalene nuclei, stretching of the C-H bond, stretching of the C-C and C-O bonds, bending of the C-N bonds and the stretching of the C-C and C=C bonds in naphthalene nuclei [10,11]. The Raman spectrum of P5A1N electrosynthesized onto the Au electrode covered with the RGO sheets highlights as the main difference in comparison to the P5A1N electrogenerated onto the blank Au electrode, a change in the value between the intensities of the Raman lines peaking at 1579 and 1620 cm −1 from 1.46 (blue curve in Figure 9) to 1.87 (red curve in Figure 9).…”
