Hybrid Cassie-Wenzel model for droplets on surfaces with nanoscale roughness.

Abstract

Several models have been developed to predict the contact angle of a droplet sitting on a roughened surface; however, no such model has been developed for substrates with nanoscale surface structures. In this paper we propose a hybrid Cassie-Wenzel model, which considers two factors attributed to the breakdown of macroscopic predictions, including the width… (More)
