Figure 5. Super-hydrophobicity, tunable wettability and transmittance of the hierarchical pattern of gold film on biaxially pre-strained substrate with simultaneous relaxation.

Figure 5

The thickness of the gold film is 13±1 nm and the biaxial pre-strains in the substrates are 250%. The static contact and roll-off angles of water drops on the pattern as functions of the biaxial compressive strain in the gold film or tensile strain in the substrate (a). The transmittance of the pattern on substrate as a function of the biaxial compressive strain in the gold film or tensile strain in the substrate (b).
