A protocol for contact angle measurement. The contact angle (Θ) itself is defined as the . The most prevalent technique for characterizing wettability is the measurement of contact angles. Unfortunately, the routine assessment of . Advancing and receding contact angles were .
Scanning confocal microscopy was used for contact angle measurement of individual microspheres. To further improve the wettability of molten metal on ceramics, contact angle of. With up to three axes for sample positioning, the sample is moved quickly and reproducibly to the measuring positions. This paper presents an automated contact angle measurement method mainly including image segmentation and curve fitting steps.
Measurement of the contact angle with . Water contact angle measurements are broadly used for the surface characterization of materials – i. In the image segmentation. Schematic diagram of the Wilhelmy plate technique for contact angle measurement. In microfluidics they are of special . Gravity-induced sagging can amplify variations in goniometric measurements of the contact angles of sessile drops on super liquid-repellent surfaces.
