Fabrication of carbon microcoil/polyaniline composite by microemulsion polymerization for electrochemical functional enhancement

Carbon microcoil/polyaniline (CMC/PANI) composite was synthesized by the microemulsion polymerization in the presence of CMC. In this novel approach, the fabrication and thermal stability of the CMC/PANI composite were confirmed by the FT-IR absorption spectroscopy and the thermogravimetry. Scanning and transmission electron microscopy was used to characterize the microstructure of the CMC/PANI composite: From these observations, it was confirmed that CMCs were uniformly coated with PANI. Finally the enhanced electrochemical behavior of the CMC/PANI composite was proved by the cyclic voltammetric study, promising their utilization as a thermally stable electrode material.

A novel surface modification by polyaniline on helical 2-dimensional carbon microcoils was achieved by the bottom-up O/W emulsion polymerization, and the polyaniline-coated CMC composites revealed the enhanced electrochemical property.Figure optionsDownload as PowerPoint slideHighlights
