Raman spectroscopic investigation of the woodceramics derived from carbonized tobacco stems/phenolic resin composite

Woodceramics samples derived from carbonized tobacco stems and different contents of phenolic resin, using different carbonization temperatures have been investigated by Raman spectroscopy. It was found that the full width at half maximum (FWHM) and the R-value decreased with an increase of the carbonization temperature and the content of phenolic resin. And the crystallite size La of these samples show low microcrystalline size, i.e. La varying between 1.85 and 5.40 nm. The results obtained indicate that 973 K is the turning point temperature for the preparation of woodceramics. The results of Raman spectra were confirmed by SEM results of the woodceramics.
