Wetting behavior of water droplet on the heterogeneous SAM-modified surface:

A molecular dynamics study

Abstract

Our study investigated the wetting behavior of water droplet on a chemically heterogeneous surface which was modified by two distinct types of self-assembled monolayer (SAM) molecules with hydrophilic and hydrophobic terminals, resulting in the formation of a soft matter-based surface exhibiting zebra-like stripes pattern. Furthermore, the pinning phenomenon near the contact line is explored.
