To optimize the sugar template employed in the formation of
the PDMS sponge, we prepared three different sugar particle
sizes: granulated (400500 μm), sanding (10001100 μm),
and black (15001800 μm) sugar (Figure 2a). By mixing these
sugar particles, we were able to adjust the template of the PDMS
sponge to obtain higher absorption capacities. Figure 2b shows
