Fabrication process and photos of the PDMS/MS composite. (a) Schematic of the PDMS/MS composite using the sugar templating process with precursor solution. The empty spaces of the sugar cube are filled with the PDMS/MS precursor owing to capillary effect. (b) FE-SEM images of 3-D porous structure of the PDMS/MS composite. MS are arranged and exposed on the surface of the PDMS/MS composite structure. (c) Photographs of fabricated 3-D porous structure and mechanical deformation under various modes; compression, stretching, twisting and bending. (Scale bar: 1 cm).
