The Study of Hexagonal Lattice Pattern Formation of Polystyrene Thin Films

In this study, we investigate and fabricate two-dimensional ordered lattice structure by breath figures method. The breath figures pattern was prepared with the solution of carbon disulfide (CS2) doped with 1% weight concentration of polystyrene. The temperature and the humidity were controlled at ~23¢J and ~60 %, respectively. The breath figures pattern began to expand while CS2 is under evaporation. We explored the relationship between self-assemble of the water droplet and ordered structure via the solution height, the temperature evolution, and the dynamical optical images in the formation process of breath figures pattern. It was found that the radius of the water droplets varying with time follows the power law, £l ~ t £go; £g0=0.76. The fast Fourier transformation and Voronoi Diagram were used to conform that the formation of the breath figures pattern varied form a disordered state to an ordered state with the evaporation of CS2. The understanding of the breath figures pattern provides us to fabricate the photonics with size from nano- to micro-scale and to improve the application of nano device.
