Claim:
1. A method of forming a film of aligned s-SWCNTs on a substrate, the method comprising: (a) partially submerging a hydrophobic substrate in an aqueous medium; (b) supplying a flow of a liquid solution to the aqueous medium, the liquid solution comprising semiconductor-selective-polymer-wrapped s-SWCNTs dispersed in an organic solvent, whereby the liquid solution spreads into a layer on the aqueous medium at an air-liquid interface and semiconductor-selective-polymer-wrapped s-SWCNTs from the layer are deposited as a film of aligned semiconductor-selective-polymer-wrapped s-SWCNTs on the hydrophobic substrate, wherein the organic solvent in the layer, which is evaporating, is resupplied by the flow of the liquid solution during the formation of the film; and (c) withdrawing the hydrophobic substrate from the aqueous medium, such that the film of aligned semiconductor-selective-polymer-wrapped s-SWCNTs is grown along the length of the hydrophobic substrate as it is withdrawn from the aqueous medium.
