The long and short of it : An ionic liquid with good thermal stability can be prepared from 100–500‐nm‐long multi‐walled carbon nanotubes (MCNTs). The MCNTs are functionalized with a polysiloxane quaternary ammonium compound followed by a sulfonate salt. A coating of average thickness 6.5 nm comprising an ionic bilayer structure perpendicular to the nanotube surface is obtained (see TEM image).
