Title:
PLATING BRONZE ON POLYMER SHEETS
Document Type and Number:
WIPO Patent Application WO/2016/205134
Kind Code:
A3
Abstract:
An electroplated article is provided comprising a polymeric substrate bearing an electroplated metal layer comprising copper and tin in an atomic ratio of less than 96:4, in some embodiments less than 87:13 and in some embodiments less than 82:18; wherein the atomic ratio of copper to tin is greater than 55:45, and wherein the electroplated metal layer comprises at least 3.5 weight % tin. The electroplated metal layer comprises an alloy having a melting point of less than 1050 ℃ and in some cases less than 800 ℃. The electroplated metal layer has a Young's Modulus of less than 15.0 GPa, in some embodiments less than 13.0 GPa, and in some less than 10.0 GPa. In addition, an electroplating solution is provided comprising Cu(II) ions, Sn (II) ions, Zn(II) ions, l-methionine, and no cyanide anion.
