Abstract

Complex multilayered thin-film architectures are fabricated by sequentially stacking mesoporous and macroporous layers with varying structure and properties. A series of deposition–stabilization steps are used to sequentially deposit the component layers of the films in order to obtain interconnected systems with a precise ordering of accessible cavities, as shown in the figure.
