▎ 摘　　要

Herein we report a novel covalent triazine framework (CTF) based on the s-triazine core. The CTF was in situ prepared onto the surface of reduced graphene oxide (rGO) via the condensation of trishydrazino-s-triazine with terephthaldehyde (TPA) or isophthaldehyde (IPA) via hydrazone linkage using both conventional heating (CFTx-rGO) and ultrasonic method (CFT1-rGOus). The resistivity and conductivity studies showed that CFT1-rGOus showed a good attachment onto the surface of rGO via the non-covalent functionalization approach (pi-pi stacking) and showed the highest resistivity materials applications with very promising character, even with high temperature. While the prepared composite using conventional heating CFTx-rGO showed at the room temperature and high-temperature studies, it is the best among the prepared materials for the conductivity.
