Resonant Raman Characterization of Polyparaphenylene Based Carbon Materials
Published online by Cambridge University Press: 10 February 2011
Abstract
The structure of the polymer polyparaphenylene (PPP), heat-treated at temperatures (THT) between 650°C≤ THT ≤750°C and prepared according to either the Kovacic or the Yamamoto methods, is studied by the resonant Raman technique using five laser excitation energies Elaer in the range 1.92–3.05 eV. The resonant Raman analysis allows identification of the benzenoid and quinoid forms of PPP as well as the amorphous material associated with the onset of the carbonization process. The results enable us to follow the evolution of the PPP polymer with heat-treatment temperature and to determine the differences between the materials prepared using the two different methods.
