Self-assembled honeycomb polycarbonate films deposited on polymer piezoelectric substrates and their applications

Self-assembled honeycomb polycarbonate films were deposited on polymer piezoelectric (poled polyvinylidene fluoride) substrates under a fast dip-coating process. Ordered structures with micro-scaled pores dispersed in the polycarbonate matrix were obtained, demonstrating two-dimensional (2D) hexagonal packing. A theoretical model explaining the self-assembling process is proposed. Fabricated structures have a potential as 2D tunable photonic crystals. Photonic band-gap location was estimated. Visible-IR transmittance spectrum of the self-assembled films was studied with a FT-IR spectrometer. Diffraction properties of the honeycomb patterns were investigated. High transparency of the components makes possible IR optics applications of obtained structures. Copyright (c) 2005 John Wiley & Sons, Ltd.
