Adhesion Studies using a Model Adherent. A domed disk-shaped epoxy, with leaflet like protrusion from its base (Figure ) was used as a model adherent. Such a domed disk makes flat contact with the coating and mimics the geometry of many natural foulants, which have bulky central structures, but they adhere to a substrate by releasing adhesives that spread as thin films ahead of the central bulky region. With such a geometry, crack has to first nucleate from the central region of contact and then propagate outward against another pinning force arising from the bending deformation of the leaflet structure. All these pose a challenging condition for release in response to external perturbations. In order to provide proof of the concept as depicted in Figure , we carried out various types of detachment studies using a 650 µm thick as PDMS film with and without the hydrophilic inclusions.
