摘要
利用红外光谱对不同共混比例的聚萘二甲酸乙二醇酯(PEN)/聚对苯二甲酸乙二醇酯(PET)共混纤维内部结构进行研究,结果表明:由于萘环比苯环有更强烈的共轭效应,所以C-H伸缩振动峰、亚甲基的振动峰、指纹区的特征峰和芳环上相邻C-H的变形振动峰在共混后都存在向低频方向移动的趋势。
The inner structures of different proportions of PEN/PET blend fiber were studied by using IR.The results showed that the conjugation effect of double benzene nucleus was more intense than benzene ring,so C—H stretching vibration peak,methyl peak,the characteristic peak of the fingerprint and C—H deformation vibration peak adjacent to aromatic ring moved to low-frequency region in blends.
