Fig. 7From: Surface Nanostructures Formed by Phase Separation of Metal Salt–Polymer Nanocomposite Film for Anti-reflection and Super-hydrophobic ApplicationsComparison of water contact angle measurements of silicon wafer with and without nanopillars formed by metal salt–polymer film. The nanopillars were fabricated by using a ANN:polymer. b CNN:polymer metal salt with different weight ratios show super-hydrophobic properties with above 160° contact angle with the surfaceBack to article page
