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 2D hexagonal packaging. Theoretical model explaining self- assembling process is proposed. Fabricated structures have a potential as 2D tunable photonic crystals. Photonic bandgap location was estimated. Visible-IR transmittance spectrum of the self-assembled films was studied with a FTIR spectrometer. Diffraction properties of the honeycomb patterns were investigated. High transparency of the components makes possible IR optics applications of obtained structures.
