| 摘 要： | 将聚对苯二甲酸乙二醇酯(PET)纤维置入过冷态的聚乙二醇(PEG)和聚己二酸丁二酯(PBA)熔体,制备了PET纤维/PEG基体和PET纤维/PBA基体复合体系。使用偏光显微镜和原子力显微镜研究了这两种异质复合体系的界面结晶形态,利用接触角测量仪测量了附生结晶法改性前后PET纤维织物的接触角。结果表明,纤维置入温度和结晶等条件决定附生体系的横穿晶体形态结构,选取合适的树脂并采用附生结晶的方法可明显改善PET纤维织物的表面浸润性,并有望改善PET纤维增强复合材料内部的界面结构。

| Abstract: | By introducing poly(ethylene terephthalate)(PET) fibers into supercooled molten poly(ethylene glycol)(PEG) and poly(butylene adipate)(PBA) matrices,fiber/matrix composites of PET/PBA and PET/PEG have been prepared.Their interfacial supermolecular structure was studied by polarizing microscope(POM) and atomic force microscope(AFM).The contact angle of water on PET fiber fabric was analyzed before and after epitaxial crystallization.The results show that the fiber introduction temperature and crystallization temperature control the interfacial transcrystallinity structure between PET fiber and the matrix.Epitaxial crystallization and employment of suitable resin matrix can significantly improve the surface wettability of PET fiber,which can probably improve the interfacial compatibility in PET fiber reinforced composite. |
