Abstract

Asymmetric Multilayers A mixture of colloidal particles is stratified according to differences in their interfacial activity at the air-water interface. Upon lateral compression, the less active particles desorb into the subphase, where depletion pressure exists, while the more active particles remain at the interface, forming a nearly perfect layered film with controllability, versatility, and scalability.
