Abstract

Nickel can be plated onto plastic, for example a MYLAR* brand of polyvinyl terphthalate, very simply, by exposing a solution of nickel sulfate with concentration NH(4)OH to adjust the pH to slightly basic (blue-green), and some sodium hypophosphite, to ionizing radiation. Optimum conditions occur when:. NiSO(4) . 6H(2)O 344 g/1 NH(4)OH - to color solution blue-green (pH = 7.8 - 8.0) NaH(2)PO(2) . H(2)O 1.8 - 2.2 g/1.

Plating Plastic With Nickel

Nickel can be plated onto plastic, for example a MYLAR* brand of polyvinyl terphthalate, very simply, by exposing a solution of nickel sulfate with concentration NH(4)OH to adjust the pH to slightly basic (blue-green), and some sodium hypophosphite, to ionizing radiation. Optimum conditions occur when:. NiSO(4) . 6H(2)O 344 g/1 NH(4)OH - to color solution blue-green (pH = 7.8 - 8.0) NaH(2)PO(2) . H(2)O 1.8 - 2.2 g/1.

This solution is exposed for 5-15 min behind the plastic to be plated, to X- rays of varying wattage. (In general, as wattage increases exposure time decreases.) The solution tolerances are great, with nickel concentration variances allowed from saturated NiSO(4) . 6H(2)O to about 100 g/l, and the solutions can be reused several times. The nickel plate is adherent, and can itself be plated, for example with copper. * Trademark of E. I. du Pont de Nemours & Co.
