荷葉

????荷葉經(jīng)過暴雨后能夠迅速干燥，同時還能保持清潔。德國的涂料公司Sto AG模擬這種能力制造出了一種獨特的外墻涂料。這家公司復(fù)制荷葉表面高低不平的微觀結(jié)構(gòu)，制造出了一種名為Lotusan的涂料。它的自潔能力更佳，使用壽命也達到了傳統(tǒng)涂料的兩倍。

Lotus Leaf

????Germany's stucco and coating company Sto AG created a unique kind of exterior paint modeled after the lotus leaf's ability to dry quickly and stay clean after a rainstorm. Sto copied the plant's bumpy microstructure to come up with Lotusan paint, designed to stay cleaner and last twice as long as traditional paint.
