Preparation of polybenzimidazole/functionalized carbon nanotube nanocomposite films for use as protective coatings.

The article discusses the synthesis of functionalized multi-walled carbon nanotubes (MWCNT) via microwave-induced polymerization modification route and polybenzimidazole (PBI) nanocomposite films containing a percentage of functionalized MWCNT. The polymer's successful grafting to the MWCNT with a polymer layer that was several nanometers thick is addressed. Tensile test and dynamic mechanical analysis (DMA) were used to measure the mechanical properties of the nanocomposite films.
