Carbon nanotube-adsorbed polystyrene and poly(methyl methacrylate) microspheres

The carbon nanotubes were incorporate onto the surface of polystyrene (PS) and poly(methyl methacrylate) (PMMA) microspheres by a potentially scalable process. PS and PMMA microspheres were 3.0 and 6.5 μm in size and were prepared using a dispersion polymerization method. The nanotubes used were multiwalled carbon nanotubes which were synthesized using a thermal chemical vapor deposition method. It was found that multiwalled carbon nanotubes are more than 500 times cheaper than single-walled nanotubes at a similar purity.
