Electromagnetic, Morphological, and Electrical Characterization of POMA/Carbon Nanotubes-Based Composites

Table 3

Main FT-IR bands observed for POMA and POMA/CNT samples.

Contribution (cm^−1)	Assignment (based on [16–18])
3433	Formation of N-H bands attributed to protonation of the nitrogen
2800	Associated to both axial deformation of C-H from aromatic carbon and C-H stretching of the -OCH3 group in the polymeric chain
1595	Group quinoid
1494	C-N stretch benzene
1462	Stretch N, N
1247	C-N stretch in polaron structure (weak band in POMA)
1030	SO stretch of ammonium persulfate used as a beginner’s reaction
844, 755	Substituted 1, 2, 4 and aromatic substitution 1, 2, both associated with the methoxy group ortho monomer
