Three-dimensional hierarchical ZnO nanostructures have been fabricated on flexible hierarchical PDMS substrates via a combination of facile PDMS casting process and solution growth routine. Fresh rose petal was used as template for the preparation of positive and negative hierarchical PDMS substrates. Morphologies, dimensions and orientation of ZnO nanostructures grown on rose-petal-like flexible PDMS surface can be controlled by adjusting the hydrothermal reaction parameters. ZnO nanostructures grown on the hierarchical PDMS substrate were found to highly influence the surface wetting behavior. Furthermore, the photoelectrical characterizations demonstrate that the flexible device based on superhydrophobic ZnO/PDMS films showed a high sensitivity of UV light and presented potential applications in optoelectronic applications.
