Abstract

Drops of a suspension of individual single-walled carbon nanotubes in F68 Pluronic surfactant dry on glass substrates to form a “crust” at the free surface. The crust is extremely thin (∼ 100 nm) and consists of an entangled mesh of nanotubes and Pluronic. Pasquali and co-workers report on p. 29 that the convective flow associated with the drying preferentially assembles the micelles into a hexagonal arrangement, as revealed by the birefringent pattern shown on the cover. This technique is promising for developing thin, optically transparent, and electrically conductive coatings and films consisting of nanotubes.
