Professor, Department of Chemical and Materials Engineering, National Ilan University Abstract The effect of annealing on an amorphous polyetheretherketone (PEEK) film is described in this article. PEEK film samples of different crystallinity were obtained by annealing originally amorphous PEEK films. The annealed PEEK film samples were characterized a differential scanning calorimeter (DSC), ultra-violet(UV)-visible spectrometry and X-ray diffraction. The annealing temperature affected the crystallinity of PEEK film greatly after an annealing time of 50 min. Thus, an annealing temperature of 163℃ was chosen for obtaining PEEK film samp
