N2 - In this work, the dielectric properties of neat PEEK have been investigated elucidate the influence of crystalline morphology on the relaxation characteristics of the material; both cold-crystallized and melt-crystallized specimens have been examined. The measured dipolar response has been interpreted using the three phase morphological model encompassing a crystalline phase, a mobile amorphous phase, and a rigid amorphous phase. Determination of phase fractions based on dipolar mobilization across the glass-rubber (A) relaxation indicates a finite rigid amorphous fraction for both cold-crystallized and melt-crystallized specimens which is relatively intensive to thermal history and degree of crystallinity (WRAP nearly equal 0.20).
