Contact angle hysteresis in electrowetting on dielectric

doi:10.1088/1674-1056/24/8/086801

Abstract Contact angle hysteresis (CAH) is one of the significant physical phenomena in electrowetting on dielectric (EWOD). In this work, a theoretical model is proposed to characterize electrowetting evolution on substrates with CAH, and the relationship among apparent contact angle, potential, and some other parameters is quantified. And this theory is also validated experimentally. The results indicate that our theory and equation based on energy balance succeed in describing the electrowetting response of potential with significant contact angle hysteresis. The CAH in EWOD, ranging from 0^o to about 20^o in electrowetting cycle, increases with the increase of voltage and climbs up to about 20^o when voltage is increased to about 38 V, and then decreases to zero with the further increase of voltage.

Keywords: contact angle hysteresis electrowetting energy balance
