contact angle

Mittaamalla kontaktikulma, kun nestepisaraa laajennetaan ja pienennetään, saadaan etenevä kontaktikulma θ a {\displaystyle \theta _{a}} (advancing contact angle) ja vetäytyvä kontaktikulma θ r {\displaystyle \theta _{r}} (receding contact angle).
As the tilt increases the downhill contact angle will increase and represents the advancing contact angle while the uphill side will decrease; this is the receding contact angle.

Staattinen kontaktikulma voidaan määrittää ideaalisella pinnalla mekaanisessa tasapainossa olevalle pisaralle Youngin yhtälön mukaisesti cos ⁡ ( θ C ) = γ s v − γ s l γ l v . {\displaystyle \cos(\theta _{C})={\cfrac {\gamma _{sv}-\gamma _{sl}}{\gamma _{lv}}}~.} Yhtälössä γ l v {\displaystyle \gamma _{lv}} on neste–kaasurajapinnan, γ s v {\displaystyle \gamma _{sv}} kiinteä–kaasurajapinnan ja γ s l {\displaystyle \gamma _{sl}} kiinteä–nesterajapinnan pintajännitys. θ C {\displaystyle \theta _{C}} on Youngin kontaktikulma.
Interrelation between contact angle and surface tensions at equilibrium is given by the Young equation: γ S G = γ S L + γ L G cos ⁡ θ c , {\displaystyle \gamma _{SG}\ =\gamma _{SL}+\gamma _{LG}\cos {\theta _{c}},} where γ S G {\displaystyle \gamma _{SG}} = Solid-Gas surface tension, γ S L {\displaystyle \gamma _{SL}} = Solid-Liquid surface tension, γ L G {\displaystyle \gamma _{LG}} = Liquid-Gas surface tension, θ c {\displaystyle \theta _{c}} = Contact angle.

Youngin yhtälö ilmaisee kontaktikulman ja interfasiaalisen energian välisen yhteyden: γ s - g = γ s - l + γ l - g c o s θ {\displaystyle \gamma _{\text{s - g}}=\gamma _{\text{s - l}}+\gamma _{\text{l - g}}cos\theta } missä γ s - g {\displaystyle \gamma _{\text{s - g}}} on substraatin ja kaasufaasin välinen interfasiaalinen energia, γ s - l {\displaystyle \gamma _{\text{s - l}}} on substraatin ja nesteen välinen interfasiaalinen energia ja on γ l - g {\displaystyle \gamma _{\text{l - g}}} neste- ja kaasufaasin välinen interfasiaalinen energia ja θ {\displaystyle \theta } on kontaktikulma.
The Young equation relates the contact angle to interfacial energy: γ s-g = γ s-l + γ l-g cos ⁡ θ {\displaystyle \gamma _{\text{s-g}}=\gamma _{\text{s-l}}+\gamma _{\text{l-g}}\cos \theta } where γ s-g {\displaystyle \gamma _{\text{s-g}}} is the interfacial energy between the solid and gas phases, γ s-l {\displaystyle \gamma _{\text{s-l}}} the interfacial energy between the substrate and the liquid, γ l-g {\displaystyle \gamma _{\text{l-g}}} is the interfacial energy between the liquid and gas phases, and θ {\displaystyle \theta } is the contact angle between the solid–liquid and the liquid–gas interface.
