In the present work, we aimed to examine how the structure of a nanosphere array affected the contact angle between a liquid droplet and fluorinated surfaces. Four types of silica nanospheres with various diameters were stacked to form different organized arrays using a self-assembly technique. To clarify the superhydrophobicity, we proposed a modified parameter into the conventional Cassie-Baxter equation. This mathematical model presented in this study can probably shed some light on how the variation of particle size would induce the superhydrophobicity of nanosphere surfaces.
