The dewetting process of thin polystyrene (PS) film on flat and stripe-patterned substrates is presented. Different dewetting processes were observed when the thin PS films annealed at above the glass transition temperature on these different kinds of substrates. The final dewetting on the flat substrate led to formation of polygonal liquid droplets, while on the stripe-patterned substrate, the droplets were observed to align at the centers of the stripes. A possible explanation for the dewetting process on the stripe-patterned substrate is proposed.
本文介绍了薄聚苯乙烯（PS）薄膜在平坦和条纹图案化基底上的去湿过程。当薄PS薄膜在高于玻璃化转变温度下在这些不同类型的基底上退火时，观察到了不同的去湿过程。在平坦基底上的最终去湿导致形成多边形液滴，而在条纹图案化基底上，液滴则在条纹中心处排列。本文提出了条纹图案化基底上去湿过程的一种可能解释。
