Description

© 2016 Elsevier Ltd. This paper reports on the self-propulsion of a droplet up an incline, confined on a polydimethylsiloxane (PDMS) channel rendered hydrophilic through combined oxygen plasma and polyvinylpyrrolidone (PVP) treatment. Our work investigates the effects of substrate angle on the distance traveled, along with the threshold value for when gravitational force overcomes Marangoni force. A numerical simulation has been developed, where the governing equations solved using COMSOL val...
