THE MEASUREMENTS OF CRYSTALLINITY DEGREE OF PEEK
聚醚醚酮结晶度的测定

y X-ray diffraction and the on rue-an alyzing-calculus methods, diffraction Peaks for crystallinity and amorphous area in PEEK are corrected, which gives the crystallinity degree formulae of PEEK. Besides, Infrared(IR), Differential Scanning Calorimetry (DSC) and Density measurement methods are also applied to measure the crystallinity degree of different crystallizing PEEK samples.Results show that all these methods are in good agreement.
