Thermal treatment of the carbon nanotubes and their functionalization with styrene

In this work we studied the functionalization of commercially available multiwalled carbon nanotubes (MWCNT) (Nanocyl 3100) with polystyrene by the method so called "grafting from". The nanotubes were used as received and oxidized in air at 400 °C. The functionalization was started using t...
