Definition of “phobicity” |
Low surface energy/low adhesion |
Low adhesion |
|
High contact angle |
Low normal strength (maximum stress) |
|
Low CA hysteresis |
Low shear strength |
|
Bouncing-off |
Bouncing-off supercooled droplets |
Interaction |
Hydrophobic interaction |
Crystallization of ice and snowflakes |
Thermodynamic relationship |
Minimization of ΔG = ΔH − TΔS |
Surface roughening transition ΔG = ΔH − TΔS = 0 and similar |
Typical manifestation of the interactions |
Hydrocarbone molecules in water environment |
Ice molecules in saturated vapor environment at negative temperatures |
Effects |
Protein folding (including fractal shape), self-organized criticality, long-range hydrophobic force, wetting transitions |
Snowlakes (diverse but symmetric, fractal) |
