Lecture 8

Question 1

Super-hydrophobicity

Answer 1

supergydrophobicity is a resuly of micro and even nano structured patterns
Contact angle > 90 degrees is superhydrophobicity

Question 2

Wenzel Regime

Answer 2

Characterized by micro-structures into which the water
droplet embeds itself

Question 3

Cassie-Baxter Regime

Answer 3

Characterized by hierarchical nanostructures that the
water droplet “floats” above
