제목 Preparation and optical properties of charge transfer type dye-dispersed fluorescent polyimide films
초록 Polyimide films have been developed for a variety of uses in many industries due to their high heat resistance and excelling mechanical durability. In general, however, polyimide films have a dark yellow color due to an intrinsic charge transfer characteristic, resulting in little fluorescence by itself. For the purpose of developing a signal output film for automotive interior sensor, we manufactured a fluorescent polymer film that charge transfer dyes are dispersed in a transparent polyimide and examined fluorescence emission properties. We first prepared a transparent polyimide varnish using a chemical imidization method, and then dispersed charge transfer type dyes to prepare fluorescent polyimide films. The imidization and transmittance were confirmed by infrared spectroscopy and ultraviolet visible spectroscopy, respectively, and quantum efficiency and photooxidative stability were examined using an optical microscope equipped with a photoluminescence spectrophotometer.
