Evaluate the influence of surface roughness on wettability

Learn a new method for correcting contact angle for surface roughness

[RECORDED WEBINAR]

 

topo_3d.pngWhile contact angle goniometry has been around for many years, we have recently developed a way to account for the underlying surface’s micro-scale roughness. This approach allows us to report the true Young’s Contact Angle (CA) by measuring and subtracting out the roughness contribution.

In this webinar you will learn more about:

  • How water sessile drop CAs were acquired at the exact same location that fringe projection phase-shifting was used to analyze the surface roughness on a wide variety of different samples.
  • how we characterized optics with anti-reflective coatings, clay tiles with gloss or matte finishes, wood polymer composite materials used for outdoor decking, and titanium materials used for biomedical implants with varying degrees of roughness.
