Abstract

Biomimetic micro‐structures are fabricated with a two‐stage pattern transfer process on conventional epoxy coatings. The pattern transfer process uses a soft‐polymer negative stamp, where the flexibility of the stamp allows for easy conformation to both flat and curved surfaces. The hydrophobicity and friction behavior of the micro‐patterned epoxy coatings are systematically investigated, showing that surface patterning can be used as an effective way to improve hydrophobicity while reducing the surface adhesion and friction without a loss of the structural integrity or rigidity typical of epoxy coatings. This work demonstrates a feasible process for the utilization of biomimetic micro‐patterns within large‐scale industrial applications to improve the performance of conventional epoxy coatings.
