Silver-containing precursor and product articles containing cellulosic polymers

Abstract:

An article has a substrate and a pattern of a dry silver nanoparticle-containing composition comprising at least 20 weight % of one or more (a) polymers, that are cellulosic polymers; (d) silver nanoparticles having a mean particle size of 25-750 nm and present in an amount of 0.1-400 weight %, based on the total weight of the one or more (a) polymers; and (e) carbon black in an amount of 5-50 weight %, based on the total weight of the one or more (a) polymers. Such patterns can have multiple fine lines of any geometric arrangement. The article can have multiple patterns of this type, and each pattern can be electrolessly plated with a suitable metal such as copper to provide electrically-conductive product articles.
