Electrophoretic Deposition of Carbon Nanotubes on Metallic Surfaces
A method based on electrophoretic deposition has been developed to produce uniform deposits of multi-walled carbon nanotubes on stainless steel substrates. Aqueous suspensions were used under constant voltage conditions in the range of 5 to 50 V, with deposition times ranging from 0.5 to 10 minutes. The thickness of the coatings was controlled by variation of voltage and deposition time during EPD. Coatings of up to 100μm thickness were achieved, which exhibit homogeneous microstructure. The EPD technique is fast, cost-effective, and it can be applied to complex shapes. Possible applications of CNT coatings are in heat extraction devices or porous nanostructured coatings for tissue engineering scaffolds.
