一种荷叶效应涂层的制备

Composite coatings with lotus effect were fabricated via imbedding micro-silica and then nano-silica. The micro-silica and nano-silica was subsquently fixed on the surface to form hierarchical micro- and nano-structures, and at the same time, the epoxy resin modified by low surface free energy material was coated on the coatings. The staic contact angle of the coatings is as high as 165° and the tilt angle for 6.5 μL water droplet is as low as 2.5°. The coatings show the similar hydrophobic capability and structure to lotus leaves.     

仿荷叶表面研究进展

近年来,荷叶表面的自清洁功能引起人们极大的研究兴趣,这种自清洁功能源自于表面形貌与低表面能物质的共同作用.目前,已用不少方法来制备仿荷叶表面.本文回顾近年来仿荷叶表面研究成果,探讨仿荷叶表面研究与发展趋势.     

一种多尺度仿生超疏水表面制备

A multi-dimension bionic super-hydrophobic surface was prepared by embedding nano-silicaon on the sandblasted aluminum surface. After surface modification by perfluoroalkyltriethoxysilame, the surface shows the similar capability and structure of lotus leaves. the super-hydrophobic surface shows static contact angle as high as 173° and tilt angle as low as 2.5° for 6.5 μL water droplet.
