Mimicking natural superhydrophobic surfaces and grasping the wetting process: A review on recent progress in preparing superhydrophobic surfaces

► We review the most recent progress in preparing superhydrophobic surfaces. ► The fundamental theories of wetting phenomena are investigated. ► The natural models inspiring to the creation of superhydrophobic surfaces are inspected. ► The main discussion focuses on the formation of surface roughness and structure. ► We present the creation of superhydrophobic surfaces through a variety of techniques.
