Abstract:
We have measured the Raman spectra of all samples in the process of preparing polyacrylonitrile (PAN) iron complex nanofibers, and compared their Raman spectral characteristics, and thus gained a preliminary result for the PAN nanofibers structural changes in the different stages. Through its Raman spectral analysis and comparison we can find that the cyano group (C N) of modified PAN nanofibers disappeared while the Raman bands of C = N group appeared. For the pre-oxidized PAN nanofiber, because the D and G bands of the C = C vibration appeared in the Raman spectra, it is concluded that the PAN nanofiber has an apparent structural change. Finally, it is also found that that Fe 3+ and O 2- ions have formed coordination bonds in the further prepared PAN iron (Fe 3+ ) complex nanofibers because the characteristic Raman band of Fe = O bond appears.
