Abstract: An improved self-assembly mechanism of polystyrene (PS) colloidal microspheres at the water-air interface is proposed and studied systematically. We conclude that to achieve the multi-layer selfassembly, it should satisfy the following two requirements: 1) the density difference between PS microspheres and the dispersion medium should be small enough to enable the PS microspheres to reach the water-air interface easily; 2) The wettability of PS microspheres assembled at the waterair interface changes from wetting to non-wetting with the evaporation of dispersion medium, which allows the water-air interface to stay at the bottom of the assembly body for the continuous self-assembly process. To confirm our conclusion, experiments in combination with theoretical calculations are offered in this article.
