Abstract Details

2017, Doctor of Philosophy, Ohio State University, Mechanical Engineering.
Nature can be turned to for inspiration into novel engineering designs that help address scientific difficulties. Through evolution, nature has created efficient and multipurpose objects using commonly occurring materials. These objects have many applications that can aid humanity and can be of commercial interest. One technical difficulty that nature can help solve includes liquid repellency. Inspiration for extreme liquid repellency, also known as superliquiphobicity, can be found on lotus leaves (Nelumbo nucifera) due to their extreme water repellency. The motivation for studying the surface of lotus leaves is that their unique surface features can be adapted for commercial applications to save time, money, and lives. Nature has a limited material toolbox, but by incorporating synthetic materials and better manufacturing processes, the surface properties can be enhanced. Mimicking these biological structures and using them for design inspirations is the field of biomimetics. In this thesis, an introduction chapter on biomimetics and liquid repellency is first presented. These principles are referred to throughout the thesis for creating superliquiphobic surfaces. Next, a chapter on experimental procedure and sample characterization is presented. Afterwards, three chapters are presented containing original research on surfaces inspired by lotus leaves for liquid repellency. Lotus leaf surfaces were created with several manufacturing methods including spray coating, vapor and spin coat deposition, and micropatterning. These surfaces were characterized for liquid repellency using contact angle and tilt angle with water and hexadecane and in some cases using shampoo and laundry detergent. This work provides discussion on optimal design as well as valuable insight for superliquiphobic surfaces. The objective of studying these surfaces was to understand their underlying principles for improved surface design in superliquiphobic applications. This design knowledge has applications in a wide variety of industries as surfaces with these properties continue to develop and the number of applications requiring these properties increase.
