Enhanced Thermal Stability of Electrical Conductivity of Polyaniline Films with Polymeric Dopants |
| 초록 |
We report the enhanced thermal stability of electrical conductivity of polyaniline (PANI) films doped by polymeric sulfonic acid dopants. We employed ladder-typed sulfonated polyphenylsilsesquioxane (S-PPSQ) as a dopant. PANI film with polymeric sulfonic acid dopant exhibit enhanced heat resistance of electrical conductivity compared to that with conventional molecular dopant, camphorsulfonic acid (CSA). The PANI films doped by S-PPSQ show a high electrical conductivity. The electrical conductivity of PANI doped by polymeric dopant S-PPSQ was retained its initial electrical conductivity after heat treatment at 120 ℃ for 10 hour, while PANI doped by molecular dopant CSA was showed a 50 % decrease in electrical conductivity. |
