Photoimage, morphology, and water contact angles of the pristine and superhydrophobic elastomer. (a) The superhydrophobic elastomer was opaque due to the presence of silica particles embedded. (b) The typical thickness of the composite layer is around 70 µm. (c) and (e) SEM images of the pristine and superhydrophobic elastomer. The superhydrophobic elastomer surface show homogeneous hierarchical microscale roughness. (d) and (f) The water contact angles on the pristine and superhydrophobic elastomer surfaces are 99.6° and 151.2°, respectively.
