We report a study to develop ‘highly fluorinated polymer-inorganic hybrid materials’ and their dispersions in fluorous solvents. Because of their limited interactions with conventional organic materials, the fluorous solvents are regarded to be advantageous processing media in constructing multi-layered organic electronic devices by solution processing. With the help of an efficient coupling reaction between amine-functionalised BaTiO3 and polymer chains modified with N-hydroxysuccinimide (NHS) ester group, it was possible to recover the highly fluorinated organic/inorganic nanocomposite, BTO-PFDMA. The dispersion of BTO-PFDMA with highly fluorinated negative-tone photoresist polymer, P(FDMA-r-GMA), in a hydrofluoroether solvent, showed sufficient dispersion stability and spin-casting properties. Thin films of polymer-inorganic composite materials were fabricated by spin-casting method and patterns as small as 10 μm could be built by UV exposure and rinse with a fluorous solvent. |
