Fig. 6From: Surface Nanostructures Formed by Phase Separation of Metal Salt–Polymer Nanocomposite Film for Anti-reflection and Super-hydrophobic ApplicationsEffects of surface nanostructures formed by metal salt:PMMA film on reflectivity in visible region. a Reflectivity measurement of silicon wafer having nanostructures formed by using ANN:PMMA film with different metal salt–polymer weight ratios and bare silicon wafer. b Reflectivity measurement of silicon wafer having nanostructures formed by using CNN:PMMA film with different metal salt–polymer weight ratios and bare silicon wafer. Reflectivity is reduced to 2% by using 5:10 ratio. c Photo of silicon wafers before and after surface nanostructuring. Reflectivity with respect to bare silicon wafer was drastically reducedBack to article page
