How does the furan ring's position and substitution affect the type of carbon formed during charring?

Label:chem

Topic
Raman spectroscopy was used to gain insight into the type of carbon formed in carbonized samples.
Answer
Based on Raman spectroscopy, the type of carbon formed was not significantly affected by the furan ring substitution and network position. The similar ID/IG ratios (1.09 ± 0.02 for PolyFDE, 1.05 ± 0.12 for PolyMethyl-FDE, and 1.09 ± 0.12 for PolyTGDFDA) suggested that an amorphous carbon with minimal graphitic structure was formed across all systems.
