The cover depicts the topographical features of nanoconfined, enthalpically inverted immiscible polymer bilayer thin films during dewetting, with both the top and bottom layers being probed simultaneously. This formation includes an internal flat rim, in addition to the typical dewetting hole geometry, highlighting the influence of polymer–substrate and polymer–polymer interfacial interactions. These interactions, combined with the bilayer's viscoelastic properties, are responsible for generating an elastic restoring force, contributing to such topographical features. View the article.
