- Chemically and thermally stable, durable, photosensitive polymeric insulating materials are in great demand for fabrication of electronic devices. In this study, we have synthesized photosensitive polymers by mixing a host polymer and photosensitizer, and explored their chemical and electrical properties. Uniform, chemically stable, mechanically flexible pinhole-free films can be formed by spin-coating, baking and photolithography at a relatively low temperature (150C); these films are clearly defined by photolithography technique. Their electrical properties showed excellent electrical performance as insulators which depend on chemical structure of a host polymer used and photosensitizer (DAST) concentration. In particular, the insulating property was improved after photo-cross-linking reaction, which is adequate for plastic-based electronic devices such as organic thin-film transistor and flexible display.
