Resumen:
In this work we studied the functionalization of commercially available multiwalled carbon nanotubes (MWCNT) (Nanocyl3100) with polystyrene by the method socalled graftingfrom. The nanotubes were used as received and oxidized in air at 400 C. The functionalization was started using thionyl chloride under reflux, followed by a reaction with ethyleneglycol which allowed the inclusion of hydroxyl groups.The reaction of those with 2-chloropropionylchloride led to the generation of the polymerization initiator. Last, the radical polymerization of the functionalized nanotubes,using styrene as themonomer,led to new materials which were studied with thermogravimetric analysis( TGA), Fourier transform infrared (FTIR) spectroscopy, transmission electron microscopy (TEM) and ultravioletvisible (UVvis) spectroscopy.
