Title:
PLATING FILM
Document Type and Number:
WIPO Patent Application WO/2019/156007
Kind Code:
A1
Abstract:
Provided is a plating film that can exhibit a high gloss and a low contact resistance value. The plating film according to the present invention is a plating film that contains a noble metal matrix and nanodiamond particles dispersed in the noble metal matrix. The plating film according to the present invention preferably has a gloss at an angle of incidence of 60° of at least 250 GU, and/or a contact resistance value at a load of 50 gf of not more than 1 mΩ and a difference of not more than 5 mΩ between the contact resistance value at a load of 50 gf and the contact resistance value at a load of 5 gf. The nanodiamond particles are preferably nanodiamond particles provided with a surface-modifying group containing a sterically repulsive group, and are particularly preferably nanodiamond particles provided with a sterically repulsive group containing a polyglycerol chain.
