Shear-induced ordering of micellar arrays in the presence of single-walled carbon nanotubes Academic Article uri icon

abstract

  • Among the more relevant additives are functional nanostructures, such as single-walled carbon nanotubes (SWNTs). SWNTs are crystalline graphitic rods characterized by a diameter in the range 0.8 to 1.2 nanometers and a typical length of microns. 13 SWNTs exhibit a unique combination of electrical and mechanical properties, 13 making them a desired component in nanohybrid materials. Combining a molecular diameter and a mesoscopic length (Scheme 1), dispersed SWNTs may affect the phase diagram of self-assembling molecules, as well as the response of the system to external constraints and the formation of non-equilibrium structures … Scheme 1 A schematic drawing of a CTAB molecule and a SWNT nanostructure … Here, we report our observations of the formation of well-aligned arrays of elongated micelles in a system composed of anisotropic molecules (cetyl trimethyl ammonium bromide (CTAB)) and a low …
