Enhancement in condensation heat transfer has the potential to increase the energy efficiency of these steam power plants by up to 2%, demonstrating a key potential impact on the global energy landscape as well as our carbon footprint. Dropwise condensation on hydrophobic thin films (~100 nm-thick) has the potential to achieve remarkable heat transfer.

Although degradation due to steam condensation has been described as ‘blistering’, no satisfactory insight exists capable of elucidating the driving force for film delamination. This dissertation focuses on designing thin and robust hydrophobic coatings for long-term dropwise condensation. We begin by investigating two mechanisms of coating failure: 1) microscopic condensation-induced blistering, and 2) mesoscopic capillary peeling. We revealed the important role of coating adhesion and pinhole defects on coating’s durability. The findings were leveraged to design, develop, and demonstrate two classes of durable and thin hydrophobic coatings materials: 1) ultra-thin, self-healing dynamic polymer networks that resists pinhole defects, and 2) lipid-like high adhesive coating interfaces, which prevent coating delamination by well-designed van der Waals interaction between the coating and the substrate.
