A conducting poly N-vinylcarbazole–molybdenum blues nanocomposite from N-vinylcarbazole–Mo VI polymerization system

Abstract

Oxidative polymerization of N-vinylcarbazole (NVC) was achieved in bulk (65 °C) and in CHCl 3 (70 °C) by Mo VIO 3 and by ‘molybdenum blues’ (MB) prepared by the reducing MoO 3 with SnCl 2. Formation of poly N-vinylcarbazole (PNVC) and its subsequent incorporation in these composite systems was endorsed by FTIR spectral analyses. Scanning electron micrographic analyses revealed the presence of very small spherical particles in MB and lumpy aggregates in PNVC–MB composite system, respectively. Thermogravimetric stability studies showed overall thermal stability trend as follows: MB > PNVC–MB > PNVC. The dc conductivity values (S/cm) of the PNVC–MB composite obtained in the present study were 10 −2—a value 10 12 fold improved compared to that of the unmodified PNVC (10 −12 to 10 −16).
