A Bio-design of Superhydrophobic Nano-coating from ZnO and Studies of Its Green Photoluminescence Inspired by Lotus Leaf

摘要

Inspired by green lotus leaf, we bio-designed a super-hydrophobic gel nanocoating with green photo-luminescence. The ZnO ingredient was prepared by sol-gel method and then modified with stearic acid (STA) to obtain superhydrophobic nanocoating. The microstructures, wettability and photoluminescence of the ZnO were characterized by scanning electron microscopy, X-ray diffraction spectroscopy, contact angle analysis and fluorescence spectrophotometry. The experimental results of ZnO-STA show excellent superhydrophobicity on various substrates and intense green luminescence. These findings can open a new view for luminescent devices with self-cleaning advances.
