Post-annealing Effect on Surface Wettability by Electron Beam Evaporated Ag/In2O3 Thin Films

Effect of post-annealing on surface wettability were reported by Ag/In 2 O 3 thin films. Ag and In 2 O 3 thin films were synthesized by a high-vacuum coating unit with an electron beam power supply. The prepared samples were annealed at 800 °C to check out the surface modifications. The field emissi...

Description
Summary:Effect of post-annealing on surface wettability were reported by Ag/In 2 O 3 thin films. Ag and In 2 O 3 thin films were synthesized by a high-vacuum coating unit with an electron beam power supply. The prepared samples were annealed at 800 °C to check out the surface modifications. The field emission scanning electron microscopy (FESEM) and atomic force microscopy (AFM) measurement were performed to analyze the surface roughness. The annealed sample shows the transition of hydrophilic to superhydrophilic with the decrease in water contact angles. All of the improved parameters demonstrate that the annealed sample has better switching features than the unannealed samples, which can be a potential candidate for smart tiles, antifogging, and self-cleaning surface applications.
