Development of Low-cost Mass Production Process of Superrepellent Surface using Doubly Reentrant Structure Pillar Array

Abstract

A new fabrication process of a superrepellent surface using a doubly reentrant structure pillar array was developed. The proposed process applying a soft-lithography is simple, low-cost, and mass-productive process compared to the conventional process. It enables to fabricate a doubly reentrant structure pillar array on glass, silicon, and PDMS substrates.
