This document discusses hydrophobic coatings and provides information on: 1. The group members working on hydrophobic coatings and definitions of hydrophobicity relating to a material's ability to repel water based on its contact angle. 2. Techniques for synthesizing hydrophobic coatings including sol-gel synthesis, molecular beam epitaxy, surface functionalization, and chemical vapor deposition. 3. Potential applications of hydrophobic coatings in de-icing, anti-fogging, self-cleaning, and anti-wetting and how this can provide benefits like increased lifespan and usability of substrates.
