Abstract	In this paper, The polyamic acid/MWNTs (PAA/MWNTs) hybrid solution were synthesized by polymerization process with 4,4′-Oxydianiline(ODA) and Pyromellitic dianhydride (PMDA) in N,N-dimethylacetamide (DMAc) in which MWNTs (modified by Fenton reagents) had been dissolved. After the imidization, PI/MWNTs ternary hybrid films were obtained. Fourier transform infrared spectroscopic (FTIR) spectra of modified MWNTs indicated that hydroxy and carboxy were introduced to MWNTs after modification. The surface and cross-section morphologies of the films were investigated by scanning electron microscopy (SEM). Dielectric properties of PI/MWNTs ternary hybrid films were studied including dielectric permittivity (ξ), dielectric loss and volume resistivity. The results indicated that the dielectric permittivity (ξ) and loss were enhanced in PI/ MWNTs ternary hybrid films as compared to the PI films.
