用傅里叶变换红外分光光度计测定不同条件下退火处理的聚对苯二甲酸乙二酯膜的谱图,用谱带分离技术对归属于反式构象的1340cm~(-1)谱带进行阻尼最小两乘分峰处理,结合属左右式构象贡献的1454cm~(-1)谱带,用线性回归分析的方法获得晶区反式构象、非晶区反式构象、非晶区左右式构象的百分含量.
The Fourier transform infrared spectrophotometer was used to measure the spectra of the annealed polyethylene terephthalate films under different conditions. The 1340cm -1 band assigned to the trans conformation was band-separated By the least square two-step damping process, the 1454cm -1 band contribution of left and right conformational contribution was obtained, and the transconformation, the trans-conformation of the amorphous region and the left-right conformation of the amorphous region were obtained by the linear regression analysis Of the percentage.
