Abstract
To manufacture printed devices, the wetting and dewetting of inks on a plate is an important factor to achieve precise printing. The Wilelmy plate method is more precise than sessile drop method, but has never been applied to polymer films with different film sides as used in printable electronics. In this study, we applied the Wilhelmy plate method to unilaterally affixed polymer film and found a good agreement between the dynamic contact angles of affixed films and the corresponding original films. This provided the usability of Wilhelmy plate method for affixed film.
