Abstract
The method of the invention produces nickel structures from nickel-coated polymer substrates. The nickel-coated polymer substrate has a nickel outer layer and initially has a temperature where the outer nickel layer lacks burst openings. Rapidly exposing the nickel-coated polymer substrate to a temperature of at least about 600.degree. C. thermally decomposes the polymer substrate and bursts holes through the outer nickel layer. The gases resulting from the thermally decomposed polymer substrate escape through the holes through the outer nickel layer to leave a nickel structure. Finally, annealing the nickel structure increases strength of the nickel structure to produce a ductile foam product.
