用计算机分峯法分解了不同热处理温度的聚萘酯(PEN—2.6)x射线衍射谱,由密度与结晶度囘归直线外推到结晶度100％和0％的密度值与文献[1][1]一致。PEN—2.6的结晶度随热处理温度的升高而增加。非晶区相邻大分子间的平均距离在温度不高时,随热处理温度升高而减小。
Computer-aided peak decomposition of different heat treatment temperature naphthalene ester (PEN-2.6) x-ray diffraction spectra, density and crystallinity regression line extrapolated to the crystallinity of 100% and 0% of the density value and the literature [1] [1] Consistent. The crystallinity of PEN-2.6 increases with the increase of heat treatment temperature. The average distance between adjacent macromolecules in the amorphous region decreases with the increase of the heat treatment temperature when the temperature is not high.
