Synthesis and characterization of novel conducting composites of polyaniline prepared in the presence of sodium dodecylsulfonate and several water soluble polymers

High electrically conductive polyaniline/partially phosphorylated poly(vinyl alcohol) composite films via aqueous dispersions

“…In the spectrum of P-PVA, the characteristic bands of the O-H stretching around 3250 cm -1 , the -CH 2 stretching (symmetric and asymmetric) at 2903 and 2810 cm -1 , the C-H bending at 1407 cm -1 are observed, and the absorbance peak at 1026 cm -1 is attributed to the stretching frequency of the -P-O-C-groups, and the strong absorbance peak at 1690 cm -1 is assigned to the stretching vibration of the -P=O-groups. 35 In the spectrum of the PAn ES, the characteristic peaks at 1502 and 1630 cm -1 are assigned to the non-symmetric benzene ring stretching vibration, the bonds around 1280 cm -1 are attributed to the stretching vibration of the C-N (mode of -N-benzenoid-N-), 36 the peak at 1130 cm -1 is assigned to the in-plane-bending vibration of the C-H (mode of -N= quinoid=N-and quinoid=N + H-benzenoid), 37 and the peak at 3525 cm -1 is assigned to the N-H stretching, respectively. In the spectrum of the PAn/P-PVA nanoparticles, the strong absorbance peak at 1060 cm -1 is assigned to the overlap of the absorbance frequency of the -P-O-C-groups of P-PVA and the in-plane-bending vibration of the C-H of PAn.…”

Preparation of compatible polyaniline/polyethersulfone solution blends

“…The presence of the two bands around 1,580 and around 1,460 cm -1 is assigned to the nonsymmetric benzene ring stretching mode (the ring stretching in quinoid and benzenoid units, respectively). The peaks observed at 1,240 and 1,300 cm -1 are due to the aromatic amine nitrogen (C-N stretching vibration) for doped PANi associated with the oxidation/protonation states [22]. According to Han and co-workers [23], a peak around 1,120 cm -1 can be assigned to in-plane-bending There is a slight shift observed for the peak position in the spectra of PANI/PES.…”

Poly(aniline-co-m-aminobenzoic acid) deposited on poly(vinyl alcohol): Synthesis and characterization

“…The former peak is ascribed to the π -π * transition of the benzene rings (Dupare et al 2008). The remaining peaks at 411 and 810 nm have been assigned as due to the polaron transitions (Hino et al 2006). From the UV-Vis spectrum, it is observed that with decrease in the AnHCl/m-ABA mole ratio or in other words, with increasing amount of m-ABA in the copolymer films, intensity of the polaron band decreases.…”
