(a) SEM of SPR-212 with 8 wt% Cu nanoparticles after processing to 1000°C, with (b) the overlaid elemental mapping from EDS and (c, d, e) deconvolved elemental contributions from Si, O and Cu, respectively. EDS reveals the bright several-micrometre-sized regions as aggregated copper. TEM (f) of the same sample shows copper regions at higher magnification, confirming growth and aggregation to sizes on the order of 1 µm. |
