摘要
应用衰减全反射傅里叶变换红外光谱法 (FTIR ATR)对聚乙二醇 /聚乙烯共混物 (PEG/PE)薄膜的表面组成进行测试。利用ATR校正程序 ,以相应的特征峰强度比作为定量测定的基准 ,可以减少测试误差。通过工作曲线法 ,定量地分析了共混物薄膜表面层中聚乙二醇链节和聚乙烯链节的相对组成 ,并提出了采用FTIR ATR定量分析共混物薄膜表面层组分时应遵循的基本步骤和原则。
The surface composition of the poly(ethylene glycol)/polyethylene (PEG/PE) blends was determined quantitatively using attenuated total reflectance FTIR spectroscopic (FTIR-ATR) technique. The ATR-FTIR spectra were first calibrated to eliminate its absorption strength dependence on the radiation wavelength. The absorption peak area ratio was used as the calibrating basis for the quantitative analysis. A working curve as well as a working equation were then established with the results of H-1 NMR and IR measurements, and used to calculate the composition of the responding functional groups in the film surface of the PEG/PE blends.
