measurement of contact angle of lotus leaf. USA KINO provides a most proper solution for your measurement of contact angle. We measured contact angle of lotus leaf.
This is origin drop image of contact angle between water and lotus leaf.
An exported image with fitting curve and calculated result based on Young-Laplace equation fitting method.
An exported image with fitting curve and calculated result based on Ellispe fitting method.
An exported image with fitting curve and calculated result based on Spline fitting method.
An exported image with fitting curve and calculated result based on Double circle fitting method.
From calculated result based on different method, we can find out that contact angle for the same drop image will almost keep same or be changed at very small range when fitting curve is fitted drop profile correctly.
