Overview

Dynamic contact angle measurement
The contact angle is a parameter used to analyse the wetting behaviour of a liquid on a solid surface. The static contact angle describes the state in equilibrium. Dynamic contact angles describe a drop of liquid that is in motion. For example, this means measuring while a drop rolls off a tilted solid surface.

Application notes

Quantifying droplet/bubble adhesion to a solid surface in air/under liquid using DataPhysics DCAT and OCA systems
The authors designed omniphobic anisotropic covalently grafted slippery surfaces (AGSs) with highly superior stability by grafting liquid-like PDMS molecular brushes on PDMS. The AGSs presented an excellent stability for the directional transportation of droplets and air bubbles dramatically outperforming the traditional SLIPSs.
