Preparation of Nanostructured Microporous Metal Foams through Flow Induced Electroless Deposition

Figure 4

Nickel deposition from NiCl₂ [Ni] = 0.13 M solution with sodium hypophosphite as reducing agent [P] = 2.52 M. (a) Inner structure at the early stages of deposition, after passing 300 mL solution through the template when the dry weight of the resulting construct (PolyHIPE Polymer and metal deposit) was 0.87 g (scale bar = 20 μm). (b) Inner structure after passing 600 mL solution when the weight of the resulting construct was 3.2 g (scale bar = 10 μm).
