Summary:Owing to the paradigm shift in the development and utilization of energy systems from petroleum to electricity under social trend to realize sustainable society, the development of high-performance electrical devices has become increasingly important. Insulating materials are one of the key technologies for the practical application of next-generation electric devices because they must be driven at higher voltages but their complex shapes cannot be coated using current coating techniques. Therefore, the development of insulating materials with thermostability and facile electrodeposition ability is crucial for the production of high-performance next-generation electric devices. In this study, synthesis of novel polyimide with pendant dimethylaminobeonzoyloxy groups is described, with which hybrid electrodeposition coating with boehmite alumina was successfully obtained whose 10% weight loss temperature was 380 ℃.
