How to impart switchable wettability and adhesion on elastomer films (DataPhysics DCAT and OCA series)

This work provides a novel approach for achieving switchable wettability from Cassie state to Wenzel state and adjustable adhesion on elastomer films via altering the micro/nanostructured clusters distance on the surfaces. By applying an additional electrical field, the droplet motion states on the superhydrophobic elastomer surface could be dynamically controlled without any loss and contamination.

An optical contour analysis system OCA and a dynamic contact angle measuring devices and tensiometer DCAT from DataPhysics were used in this research.
