Bionic Superhydrophobic and Drag-Reduction Properties on ZnO-Nanostructured Functional Surfaces†

摘要

This manuscript reports the drag reduction of the surface coated with Zinc Oxide nanostructures. The surface is prepared by chemical vapor deposition on a silicon substrate and characterized by scanning electron microscopy. Then the slip lengths of the surface in three liquids with different viscosities are measured using a rheometer system.
