Large-scale submicron horizontally aligned single-walled carbon nanotube surface arrays on various substrates produced by a fluidic assembly method

Single-walled carbon nanotube ( CNT) arrays have been assembled on various substrates over mm-scale surface areas by combining fluidic alignment with soft lithography ( micropatterning in capillaries) techniques. The feature size of the nanotube patterns reaches down to submicrometre scale. To this end, tailored substrate surface modification and pre-alignment of chopped CNTs in suspension are highly critical.
