浸润性是固体表面的重要特征，由表面的化学组成和微观几何结构共同决定．超疏水性表面一般是指与水的接触角大于150°的表面，这种表面材料在工农业生产和人们的日常生活中都发挥着重要的作用，特别是仿荷叶的具有低吸附力的超疏水性表面在自清洁方面具有广泛的应用前景

英文摘要：

Cabbage-like polydimethysiliconalkly（PDMS） films were prepared via a laser cutting method. The as-prepared special ＂micro-submicro-nano structures＂ PDMS films have a very low adhesive force to water. The force is merely about 6.5 μN, and appears at the time just before the water droplet leaves the surface. The super-low adhesive force of rough PDMS surface results from the distinct decrease of the real contact area between the surface and water drop. The sliding feature is strongly affected by microstructure of surface. That rough structure induced on the surface of PDMS is due to the thermo-reaction of laser with transparent elastomer. This information is useful for the designing of bio-mimetic hydrophobic surface structure for various applications. These surfaces may provide very effective water-repellent and anti-adhesive properties against particular contamination. Such properties can greatly extend its applications to many other areas such as lost less liquid transportation without loss, and micro-pump（ creating pushing-force） needless micro-fluidic devices etc.
