Abstract

The soluble poly(ether ether ketone) (PEEK) containing trifluoromethyl group (FPEEK) was prepared by nucleophilic polycondensation reaction of 4, 4'-difluorobenzophenone and 4, 4′-(hexafluoroisopropylidene)diphenol in the presence of an excess of anhydrous K2CO3 with tetramethylene sulfone as the solvent. The structure and thermal stability of FPEEK were studied by Fourier transform infrared spectroscopy, nuclear magnetic resonance spectroscopy, X-ray diffractometer and thermogravimetric analyzer. The solubility of FPEEK was also investigated using different organic solvents. Then the solution of FPEEK in N, N-dimethylformamide (DMF) was applied to prepare insulating coating. The mechanical properties of the coating were tested. The results show that FPEEK is soluble in common organic solvents such as chloroform, tetrahydrofuran and DMF. FPEEK shows high thermal stability with the initial degradation temperature of 536 °C in nitrogen. The insulating coatings of FPEEK exhibit the good adhesion, flexibility and impact resistance.
