Characterisation techniques

Surface and interface analysis

  • Drop Shape Analysis for the determination of dynamic contact angles (on hydrated and dry surfaces), sliding anglessurface and interfacial tensions (one instrument with high temparture cell (up to 400°C) and one istrument with high pressure cell (700 bar at 200°C) equipped with high pressure CO2 pump)
  • Wilhelmy Balance for the determination of fibre perimeters (diameters) and dynamic contact angles
  • Spinning Drop Tensiometer
