Photoinduced Reversible Formation of Microfibrils on a Photochromic Diarylethene Microcrystalline Surface

摘要

Lotus and taro leaves have hydrophobic surfaces,which in nature consist of micrometer-scale rods or projections that exhibit a super water-repellent property called the lotus effect.The contact angle of a water droplet on such surfaces is 161.0 +-2.7 deg.Recently,many reports concerning changes in water droplet contact angle as a result of changes in surface morphology and surface polarity have been published.
