Abstract

Summary: A simple and inexpensive method for forming a low‐density polyethylene (LDPE) superhydrophobic surface by controlling the crystallization behavior of LDPE by adjusting the crystallization time and nucleation rate has been proposed. The resulting porous surface, with hierarchical micro‐ and nanostructures on the beautiful floral designs, has a water contact angle of 173.0° ± 2.5°.

A highly porous surface created by adding nonsolvent (cyclohexanone) followed by evaporation of the LDPE in a vacuum at 25 °C (left, inset shows corresponding water contact angle). Nanostructures on the florallike crystal structures (right).

## Abstract **Summary:** We describe an interesting approach to the fabrication of wettability gradients from hydrophobicity to superhydrophobicity in low‐density polyethylene (LDPE) films by first forming high porosity surfaces and placing the specimens onto linear temperature gradients. While the
