提出了一种简单而有效的方法来实现超疏水薄膜通过延长聚四氟乙烯薄膜。水接触角可以从118度增加到165度。百分之一百九十纤维状晶体和纤维状晶体之间增加的距离被认为是高水接触角的原因。结果表明，微结构的排列密度对超疏水性有重要影响。
A rather simple but yet effective way to achieve a superhydrophobic film by extending a Teflon film is proposed. The water contact angle can be increased from 118 to 165degrees by extending to ca. 190%. The fibrous crystals and the increasing distance between the fibrous crystals are believed responsible for the high water-contact angle. It indicates that the density of the aligned microstructures is very important for the superhydrophobicity.
