AbstractNew fluorinated polyimides with high heat resistance and low dielectric constants have been synthesized by a two-step procedure. The thermal, mechanical and electrical properties were measured, which indicated that the polyimides with pyridine moieties in the main chain showed both good heat resistance and mechanical properties with initial thermal decomposition temperatures of 545 similar to 601degreesC in nitrogen and elongation at break of 9% similar to 16% and tensile strength of 94.2 similar to 147.3 MPa. The polyimide films showed also good dielectric properties with dielectric constants of 2.86 2.91 at 1 MHz frequency and breakdown voltage of 150.4 similar to 197.3 kV/mm, which was mainly because of the high fluoro-content and large free volume in the molecular structures. All the properties made them great potential candidates for advanced packaging in microelectronic applications.
