Process for removal of polymer foams from nickel-coated substrates

摘要

Production of a ductile nickel foam structure comprises (i) heating a nickel-coated polymer substrate to at least 600 deg C in less than 5 seconds to thermally decompose the polymer substrate and cause gaseous decomposition products of the polymer to form a large internal pressure and burst holes through the outer nickel layer, (ii) discharging gases from the polymer substrate through the holes in the nickel layer, and (iii) annealing to increase the strength of the structure.
