WebPolyfurfuryl alcohol (PFA) is pyrolyzed at 600{degree}C for different lengths of heat-treatment (HT) time (0{endash}50 h) and at different pyrolytic temperatures (600{endash}850{degree}C) for 4 h. Analysis by Raman spectroscopy shows that the crystallite size of PFA pyrolyzed at 600{degree}C decreases with increasing HT time.
