Abstract: The surface micro-morphologies of two kinds of leaves—folium perillae and corn husk—which have excellent anti-adhesion characteristics at high temperature and wet circumstance, were investigated by scanning electron microscopy (SEM). The hydrophobicity and anti-adhesion characteristics were quantitatively measured meanwhile. Results showed that they all had non-smooth surface morphologies mounted with cilia and demonstrated favorable anti-adhesion features. Folium perillae which showed hydrophilicity, had the surface compactly pieced together by jigsaw-like plates, with stomas embedded. On the other hand, corn husk showing hydrophilicity, had the surface appeared longitudinal undulated ripples with sags and crests, and had grains on secondary microscale.
