- Abstract
- Patterning arrays of single walled carbon nanotubes (SWCNTs) is an important technological
step for a range of applications of these materials in electronics, optics, electrochemistry and biosensing.
Here, we demonstrate the fabrication of conductive networks of SWCNTs with
controlled porosity on the mesoscopic scale by two dimensional assembly, from aqueous
solutions, of monodisperse polystyrene (PS) beads carrying SWCNTs at their surface. SWCNTs
are adsorbed onto the bead surface by non covalent hydrophobic interactions. Once the PS beads
self-organize into ordered arrays, they are removed by an organic solvent, yielding a connected
SWCNTs network that retains the geometrical structure of the bead assembly. The electrical
properties of these ordered SWCNTs arrays exhibit a Mott-conducting behavior with RT
conductivity of 100 S cm21. (literal)
