Description

Cavendish Laboratory, and Department of Materials Science and Metallurgy, University ofCambridge, 2010. - 20 p.Electrohydrodynamic (EHD) pattern formation of carbon nanotube-polymer compositefilms yields well-defined patterns on the micrometer scale along with the alignment of carbonnanotubes (CNTs) within these patterns. Conductive pathways in nanotube networksformed during EHD patterning of nanocomposite films results in a substantial increase in thecomposites’ conductivity at loadings exceeding the percolation threshold. The degree of nanotubealignment can be tuned by adjusting the EHD parameters and the degree of alignmentis mirrored by the conductivity across the film. Using an etching techniques or by embeddingrelatively long nanotubes, patterned surfaces decorated by CNT brushes were generated.
