A method for depositing a coating of a nanostructure material onto a
substrate includes: (1) forming a solution or suspension of containing
the nanostructure material; (2) selectively adding "chargers" to the
solution; (3) immersing electrodes in the solution, the substrate upon
which the nanostructure material is to be deposited acting as one of the
electrodes; (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 of the coated substrate.
