Synthesis, properties and application of polyindole/TiO2 nanocomposites
Nanocomposites of polyindole (PIn) and TiO2 were prepared by chemical polymerization. The morphology of nanocomposite particles was studied by scanning electron microscopy and transmission electron microscopy. The chemical structure of conducting polymers in nanocomposites was characterized by FTIR and Raman spectra. The thermal analysis showed that all conducting polymers in the nanocomposites were stable at more than 600°C. The corrosion protection of the nanocomposites was investigated. © 2009 IOP Publishing Ltd.
