Abstract
A method of enhancing the conductivity of metal-nanomaterial hybrids includes subjecting a cathode substrate to an electrolyte solution including a nanomaterial and metal ions. The cathode substrate is spaced from a metal anode in the electrolyte solution. A pulsed waveform is applied across the cathode and anode to electrodeposit metal ions from the electrolyte solution onto the cathode substrate as a coating and to electrophoretically embed the nanomaterial in the electrolyte solution into the coating on the cathode substrate.

A method of enhancing the conductivity of metal-nanomaterial hybrids, the method comprising:
- subjecting a cathode substrate to an electrolyte solution including a nanomaterial and metal ions, the cathode substrate spaced from a metal anode in the electrolyte solution;
- applying a pulsed waveform across the cathode and anode to electrodeposit metal ions from the electrolyte solution onto the cathode substrate as a coating and electrophoretically embedding the nanomaterial in the electrolyte solution into the coating on the cathode substrate;
- and
- the pulsed waveform configured to produce a cathodic pulse which electrodeposits the metal ions onto the cathode substrate and which electrophoretically embeds the nanomaterial into the coating followed by an anodic pulse which improves deposition uniformity.
