Abstract
This study aims to investigate the application of perylenetetracarboxylic dianhydride
(PTCDA), which is also known as C.I. Pigment Red 224 (PR224), as a carbon precursor.
PTCDA has a stacking structure and planarity, thereby forming a crystal structure and good
thermal stability. Moreover, PTCDA has a very high theoretical elemental carbon content of
73.47%, which suggests that its maximum theoretical carbon yield is more than 70%.
Therefore, PTCDA was selected as a carbon precursor and compared with coal-tar pitch
and petroleum pitch, which are carbon precursors with high carbon yield and excellent
carbon crystallinity after carbonization. The initial decomposition temperature of PTCDA
was 240–328 °C higher than that of the pitches, suggesting that the thermal stability of
PTCDA is better than that of the other pithces. After carbonization, the graphite (002) interplanar
distance (d002) of carbonized PTCDA (C-PTCDA) was 3.54 Å, which was similar to that
of the pitch-based carbons. The crystal size (Lc) was the largest among the prepared carbons
with 30.03 Å. The ID/IG ratio of C-PTCDA was 2.12, which was the lowest value among
the prepared carbons. The 2D peak of C-PTCDA was observed at 2720 cm-1, suggesting the
least disordered graphite structure. Therefore, we believe that PTCDA has excellent potential
for use as a carbon precursor for highly ordered carbon materials.
