Abstract

Highly ordered mesoporous carbons (OMC) materials possess enormous potential for many high-tech applications, such as bioreactors, dielectrics, thermal insulation, sensors, and catalysts. This study explores the synthesis of two types of OMCs with distinct pore structures using the solvent evaporation-induced self-assembly method. We investigated the relationship between the degree of graphitization and the thermal conductivity of these ordered mesoporous carbon materials, which were prepared at different calcination temperatures. Small-angle X-ray scattering (SAXS) results indicate that the graphitization of FDU-16, characterized by a body-centered cubic (Im

m) pore structure, surpasses that of FDU-15, which features a two-dimensional (2D) hexagonal (p6mm) pore structure. We first establish a correlation between pore structure, degree of graphitization, and thermal conductivity in ordered mesoporous carbon materials, offering a potential solution to challenges related to insufficient thermal conductivity and ineffective thermal management in porous materials.
