The cover shows an optical micrograph of a thin film polymer blend containing conducting polyaniline doped with dodecylbenzenesulfonic acid (PANI(DBSA)) and insulating polystyrene, as presented by Jakub Haberko and colleagues on page 2354 . The sample was prepared by spin‐coating from a solution in humid atmosphere. A dynamic secondary ion mass spectrometry map of 26CN‐ ions measured on this sample show bright contrast corresponding to high concentration. The circular domains are built of polyaniline, whereas the surrounding phase is devoid of this polymer. The circular shape of these domains results from the dopant (DBSA) acting as surfactant.
