A method for depositing a patterned coating of a nanostructure material
onto a substrate includes: (1) forming a solution or suspension of
containing the nanostructure material; (2) masking at least a portion of
at least one surface of the substrate (3) immersing electrodes in the
solution, the substrate upon which the nanostructure material is to be
deposited acting as one of the electrodes or is electrically connected to
at least one electrode; (4) applying a direct and/or alternating current
electrical field between the two electrodes for a certain period of time
thereby causing the nanostructure materials in the solution to migrate
toward and attach themselves to the substrate electrode; and (5)
subsequent optional processing.
