ABSTRACT: In order to carry out in-depth research on the microchemical properties related to the aromatic structure
of carbonaceous materials and to grasp the chemical production and transformation mechanism of carbonaceous
materials. In this paper, a quantitative microcrystalline structure analysis method based on HRTEM is proposed to take
aromatic lattice fringes from HRTEM images of four carbon black samples with different sources and to quantitatively
characterize the characteristic parameters such as length, angle, curvature and stacking of aromatic lattice fringes. The
results show that the distribution patterns of microcrystalline structure are similar in different regions of the same
sample and among different samples: the number of lattice fringes decreased with increasing fringes length, short
fringes were predominant, angle and curvature distributions were scattered, stacking was mainly single-layer, and the
number
