Abstract
Herein we present a series of self standing, flexible and transferable one-dimensional photonic crystal obtained through infiltration of a polymer solution in a porous stack prepared by alternating deposition of layers of TiO2 and SiO2 nanoparticles. Since the mesostructure is uniformly filled by the polymer, it is possible to lift off the hybrid multilayers using an adequate thermal treatment to obtain a multifunctional material that combines the optical properties of the periodic nanoporous multilayer and the structural and physic-chemical characteristics of the polymer used. The use of these hybrid 1DPCs as flexible interference filters, or as 1DPC to any kind of substrate is demonstrated.
