As long as the material you are trying to deposit is conductive and has an electrical charge, you can try depositing via an electrophoretic deposition (EPD). This method is pretty facile, fast and cost effective and yields layers of good quality - nice adhesion, high density. All you really need is the power supply, prefarably with possibility to steer the voltage.
In order to be able to perform an EPD, you would have to make a stable suspension of your particles in the solvent of your choice (water, ethanol, acetone and isopropanol have proven to work good in the case of CNTs, you would have to empirically test what is the best in your case). The applicability of the solution for the purpose of EPD can be tested by measuring the Zeta potential.
Some information about the basics of the process can be found in the review I've attached. Also, I can recommend you prof. Boccaccini's articles, focused on the EPD of nanomaterials.
