摘要:
采用拉曼光谱法研究聚对苯二甲酸乙二酯（polyethylene terephthalate，PET）分子拉曼振动模式，分析比较PET纤维分别进行硫酸、氢氧化钠和硫酸铜处理前后的拉曼光谱特性．结果表明，经 NaOH处理的PET纤维，在200—1 750 cm-1内拉曼峰强度高于未经处理的PET纤维，荧光背景明显减弱；经H2SO4处理的PET纤维，拉曼峰强度显著低于未经处理的PET纤维；经CuSO4处理的PET纤维，拉曼峰强度高于未经处理的PET纤维．采用原子力显微镜对处理前后PET纤维形貌结构进行观察，测量结果与拉曼光谱结果一致，表明拉曼光谱与原子力显微镜的结合可以成为高聚物物性的表征技术．
Abstract:
In order to investigate Raman vibration modes of polyethylene terephthalate (PET), Raman spectrometry is employed to study the characteristics of Raman spectra of PET treated with or without sodium hydroxide, sulfuric acid and copper sulfate, respectively. Raman spectra under different conditions are obtained, and characteristics of the Raman spectra are analyzed. The results show that among 200—1 750 cm-1, intensities of Raman peaks for PET fibers treated with sodium hydroxide are higher than those for untreated fibers, and the fluorescence background in Raman spectra for PET treated with sodium hydroxide decreases as compared to that for untreated fibers. Intensities of Raman peaks for PET fibers treated with sulfuric acid decrease significantly affer treatment. The intensities of Raman peaks for PET fibers treated with copper sulfate increase as compared to those for untreated fiberical. The morphological structures of the PET fibers are observed under different conditions using atomic force microscope (AFM). The results obtained by Raman spectroscopy are consistent with those by atomic force microscopy, indicating that the combination of Raman spectroscopy and atomic force microscopy might be a promising technology for polymer characterization.
