Soft templating process example using the present approach.
(a) Cross pattern identical to that shown in Figure 7; (b) water drop impact with We = 100 leaves a water template of the desired pattern; (c) silver nanoparticle ink is dispensed onto the water template; (d) silver film after sintering; (e) closeup detail of (d) shows the silver film accommodating the sharp angles on the hydrophilic patterned section and not extending onto the hydrophobic area shown in black.
