Contact angle measurement

By measuring the contact angle with two types of reagents, it becomes possible to analyze the surface free energy of the material.

"Contact angle measurement" is a commonly used inspection method to assess the strength of atmospheric pressure plasma effects. A droplet of water is placed on the surface of the target material, and the angle at the point of contact with the material is measured. The smaller the value, the more hydrophilic (the better the affinity for water) the material is. Our company uses the Ellipse (Tangent-1) method, which analyzes the contour of the water droplet by tracing it as separate parts of two ellipses, as the standard analysis method. 【Other Analysis Methods】 ■ 1/2θ Method ■ Tangent Method ■ Young Laplace Method ■ Circle Method *For more details, please download the PDF or feel free to contact us.
