| 摘 要： | 以尿素/甲酰胺为复配增塑剂，采用熔融共混法制备聚乙烯醇（PVA）薄膜。通过傅里叶变换红外光谱、扫描电子显微镜、差示扫描量热仪以及力学测试对PVA薄膜的结构与性能进行表征。结果表明，尿素/甲酰胺复配增塑剂通过破坏PVA分子内与分子间的氢键而影响了PVA分子链的有序结构，在改善PVA加工性能的同时降低了PVA的结晶度，并有效提高了薄膜的韧性。

Preparation and Properties of Poly (vinyl alcohol) Films with Urea/ Formamide Complex Plasticizers |
| |
| Abstract: | A series of poly(vinyl alcohol) (PVA) films with urea/formamide complex plasticizers were prepared by a melt processing method, and their structure and properties were characterized by Fourier-transform infrared spectroscopy, scanning electron microscopy, differential scanning calorimetry and mechanical measurement. The results indicated that the urea/formamide complex plasticizer affected the ordered structure of PVA molecular chains by destroying their inter/intra hydrogen bonds, thus improving the melt processing performance of PVA and decreasing its crystallinity degree.Furthermore, the toughness of the films was enhanced effectively. |
