Hierarchical ZnO particles grafting by fluorocarbon polymer derivative: Preparation and superhydrophobic behavior

- The hierarchical particles were prepared by a simple, mild hydrothermal process.
- The obtained “chestnut” ZnO particles show dual-scale morphology with high roughness.
- FEVE derivative was creatively imported to graft onto hierarchical particles.
- Superhydrophobic surfaces were obtained, on which the contact angles surpass 150°.
- A special model was proposed to explain the wetting state in this work.
