Synthesis of PPy/Nano-Graphite Sheets/TbCl₃Composites with High Conductivity

Abstract

Nano-graphite sheets (NanoGs) were prepared by treating the expanded graphite with sonication in 95% alcohol solution. The polypyrrole (PPy)/NanoGs/TbCl 3 nanocomposites were successfully prepared by in-situ polymerization. The structure, morphology, and stability of the composites are characterized by transmission electron microscope (TEM), scanning electron microscope (SEM), and thermogravimetric analysis (TG). The PPy/NanoGs/TbCl 3 nanocomposites exhibited much higher electrical conductivity and better thermal property than the pristine PPy. The electrical conductivity of these nanocomposites were adjusted by changing different wt% of the NanoGs and TbCl 3 , the conductivity of the composites was reached 80.0 S/cm with the 7 wt% of TbCl 3 and 3 wt% of NanoGs.

Influence of pyrrole feeding ratios on physicochemical characteristics of high-performance multilayered PPy/PVC/PDA@FG-NH2 nanocomposites

“…In the same way, the lamellar structure of graphite sheets also limited the activity of PPy molecules and hence hindering the thermal decomposition reaction. 24,25,46…”
