聚对苯二甲酸乙二酯分子振动模式的特性研究
Investigation on Raman spectroscopy of molecular vibrational modes of polyethylene terephthalate
摘要
Abstract
Raman spectrometry was employed to study the characteristics of Raman spectra of polyethylene terephthalate ( PET) , which were treated with sodium hydroxide , sulfuric acid and copper sulfate , respectively .Raman spectra under different conditions were obtained , and the characteristics of the Raman spectra were analyzed .The results show that the intensi-ty of PET treated with sodium hydroxide is lower than that untreated beyond 1 750 cm -1 and the fluorescence background of Raman spectra was decreased .The spectra intensity of PET treated with sulfuric acid was remarkably reduced than that untreated , and the intensity of PET treated with copper sulphate was much higher than that untreated .The molecular vibra-tional mode of PET can be inhibited by sulfuric acid , while the vibrational mode can be trig-gered by copper sulphate .关键词
