Description

Areas of activity :
The Wettability platform includes a goniometer and two tensiometers. These devices characterise the (wetting) ability (hydrophilic/hydrophobic nature) of solid surfaces (plate, fibre, powder) and measure the superficial or interfacial tension of liquid. Measurements of dynamic or static contact angles determine the surface energy of a solid or superficial energy of a liquid. Accessories such as the humidity and temperature controlled chamber, tilt table and ultra-fast camera allow super hydrophobic or absorbent surface characterisation. It is then possible for example to measure the stall angle on super hydrophobic surfaces. 

Main equipment (strengths of the Institute) :

The wettability platform is equipped with

• 1 Krüss DSA100 goniometer,
• 1 Krüss K100 tensiometer
• 1 Krüss K12 tensiometer,
• 1 Krüss K14 tensiometer
