Synthesis and Characterization of conducting Polyaniline nanoparticle doped by Multiwall Carbon nanotube |
| 초록 |
Conducting nanoparticles based on Polyaniline treated with multi wall carbon nanotube (MWNT) were synthesized via emulsion polymerization. Cyclohexane was used for media of polymerization and various surfactants such as dodecylbenzenesulfonic acid and Naphthalenesulfonic acid were added for the formation of inverse micelles. MWNTs were purified through the acid treatment and introduced into the emulsion. Inverse micelles of surfactants and aniline monomers were adsorbed by MWNT due to the hydrophobicity of outer layer of micelle. The redox polymerization using oxidants was conducted. The product exhibited higher electric conductivity. The XRD patterns of the powder represented that the existence of MWNT had an effect on the formation of pyrrole layer near the nanotubes. The carboxy modification of MWNT and the chemical interaction between MWNT and polypyrrole were observed by FT-IR spectrum. Thermal stability of the conducting particle was improved by introduction of MWNT. |
