Filling nanoporous polymer thin films: an easy route toward the full control of the 3D nanostructure

A novel approach enabling the full control of the 3D nanostructure of polymer thin films is presented. An ordered nanoporous polymer film is obtained using a nanoparticle monolayer as template. The pores are then filled with a second organic component via spin coating which, by modulating the deposition parameters, enables the control of the filling degree with nanometric precision.
