CHROME-FREE METHODS OF ETCHING ORGANIC POLYMERS WITH MIXED ACID SOLUTIONS |
| 摘要 |
A chrome-free acidic aqueous solution of sulfuric acid and one or more organic acids and manganese (II) and (III) ions is applied to an organic polymer surface to etch the surface. The etched surface is then plated with metal. |

1. A method comprising:
a. providing a substrate comprising one or more organic polymers; b. providing an aqueous acid solution consisting essentially of sulfuric acid, one or more organic acids and Mn(II) ions and Mn(III) ions; and c. contacting the one or more organic polymers of the substrate with the aqueous acid solution to etch the one or more organic polymers of the substrate. |
