Abstract

Taking the previous research conducted, this project aims to further the study and research of the wettability of surfaces. Surface features and types are important factors to their wettability. The geometric properties of a surface can make it more hydrophobic and hydrophilic. Extreme cases of hydrophobic and hydrophilic surfaces lead to water repulsion or water absorption, even under extreme conditions. The goal of this project is to gain further insight on how fabricated 3D-printed featured surfaces and examine the wetting transition on these surfaces. In particular, cylindrical pillars will be studied with varied pillar spacing, height and diameter. In addition, the silicone surfaces will be coated with methyl, perfluoro, hydroxyl, and amino based salines. The liquid will be monitored on the surfaces through an optical microscope to determine the transitional behavior of the fluid on top and how fast the transition takes place from the non-wetting) such as seen in the Cassie-Braxter's state) to the wetting state (such as seen in the Wenzel's state).
