The progress in heat managing materials for electronic devices requires a profound understanding of the interfacial behavior between polymeric network and thermal conducting fillers. Discotic reactive mesogen (RM), RM-ene and RM-thiol were synthesized as building blocks to construct a polymeric matrix for thermal conducting composites with boron nitride (BN) or expanded graphite (EG). Although the thermal conductivity of EG is lower than BN, RM-EG composite exhibits better thermal conducting properties than RM-BN composite at same amount of filler loading. Theoretical calculation and spectroscopic analysis identified that the RM matrix shows a strong interfacial affinity with EG through π−π interaction. Whereas, the RM matrix only interacts with BN via van der Waals interaction.
