Ftir Spectroscopy: A Useful Tool for Structural Determination of Polyaniline and its Nanocomposites

Abstract

Poly(aniline) nanocomposites were obtained by polymerisation under various experimental conditions including variation of time, temperature, monomer and concentration of initiators. The ratios of imino and amino units were estimated and correlated the with polyaniline (PANI) structure. Rates of polymerisation (Rp) values were estimated by a gravimetric method. TGA counsels the thermal stability of PANI. Through FTIR study, the structure of PANI/As2O3 nanocomposites was recognised. Comparison of polyanilines produced with two different initiators was done.

One-pot synthesis of polyaniline doped with transition metal ions using H2 O2 as oxidant

“…In addition, the peak at 827 cm −1 is due to the out‐of‐plane C―H bending . All of these peaks can be associated with characteristic bands of the quinone and semi‐quinone structures in the doped samples reported previously . For both Cu‐PANI and Zn‐PANI, the characteristic peaks of quinone and semi‐quinone structures are very similar to that of the H‐PANI as seen in Fig.…”

“…The thermal properties of PANI can be increased by making nanocomposites with various metal or metaloxide nanoparticles because the added nano material can occupy the space between the polymer chains as a filler. Poly(aniline)s were made nanocomposite with CuO [17], ZrO2 [18], kaolinite [19], MnO2 [20], CdS [21], TiO2 [22], V2O5 [23], As2O3 [24], Sb2O3 [25] and ZnO [26]. By this way the thermal stability of PANI was increased.…”
