| 제목 | Synthesis of Ag/re-doped polyaniline nanoparticle composites |
| 초록 | Conducting polymer especially polyaniline (PANI) has been attracted much attention owing to many advantages: the monomer (aniline) is relatively inexpensive, the polymerization method is simple and yield to high. However, its large-scale commercial development is difficult due to its poor solubility, fusibility and thermal stability. To overcome these disadvantages, bunch of researches for improvement on processability have been widely investigated, such as synthesis of colloidal particles, substitution of alkyl chain, copolymerization with aliphatic monomers and making blends or composites with other polymers1-3. In this study, we prepared Ag/PANI re-doped by various dopants nanoparticle composites. PANI nanoparticles were synthesized from micellar polymerization4,5. Using ‘doping-dedoping-redoping’ method6, PANI re-doped by various dopants such as mercaptoacetic acid (MAA), 3-mercaptopropionic acid (MPA), mercaptosuccinic acid (MSA) and 3-mercapto-1-propanesulfonic acid (MPS) were prepared, and aqueous silver nitrate solution was added in these materials. FT-IR and UV-vis spectroscopy confirmed PANI formation. The average size of the PANI particles determined by scanning electron microscopy (SEM) was 400-500 nm and colloidal dispersions have a good long-term colloidal stability. References [1] A.G.
