Again using a metal nanostructure and microstructure for plating nickel-cobalt alloy to be reproduced, so that the resultant structure is fixed to the roller.
A metal coating is used to protect the micro-nanorice structure and reprint it in a nickel-cobalt alloy in order to secure the resulting structure to the roller.
Then, the micro nano structure is protected by metal coating and printed on Ni Co alloy, so that the obtained structure can be fixed on the roller.<br>
