Electroless metallization of carbon substrates

Results are presented on electroless metallization of carbon via the format ion of carbon nitride films. The proposed process, takes advantage of the s trong chemical affinity of palladium towards nitrogenated species to cause the chemisorption of the catalyst (Pd) on the carbon nitride films. In the present work, thin carbon nitride (CNx) films were deposited onto polycarbo nate, glass or silicon substrates by DC magnetron sputtering of a graphite target in a reactive atmosphere (pure nitrogen and nitrogen-argon mixture). Deposition parameters of CNx films were optimised for the metallization it self through photoelectron spectroscopy (XPS) and adhesion (fragmentation t est) measurements.
