Transformation of oligoaniline microspheres to platelike nitrogen-containing carbon
Original language description
Aniline oligomers are important in relation to one of the most important conducting polymers, polyaniline. In the present study, aniline oligomer microspheres have been prepared during oxidation of aniline with ammonium peroxydisulfate under alkaline conditions in 0.2 or 1.0 M ammonium hydroxide. They were subsequently converted to disordered nitrogen-containing carbons during heating to 650 °C in an inert atmosphere. Raman spectra confirm the transformation of the aniline oligomers into a material displaying two peaks assigned to graphitic and disordered modes. In contrast to polyaniline, which retains its morphology after carbonization, the microspherical morphology of aniline oligomers was completely destroyed and replaced by two-dimensional plates.The evolution of the new morphology was followed by scanning electron and optical microscopies, and the corresponding changes in molecular structure after heating are discussed on the basis of Fourier transform infrared and Raman spectro
