Abstract: PET/PVA composite nanofiber was fabricated by electrospinning，and crosslinked with glutaraldehyde vapor. The morphology of the nanofiber was characterized by SEM，and the properties of the product were measured by thermal analysis (DSC)，water contact angle and tensile test. The results showed that the PET/PVA composite nanofiber membrane had good mechanical properties and excellent hydrophilicity.

Key words: PET/PVA, electrospinning, hydrophilicity, crosslinking

摘要： 使用聚乙烯醇（PVA）对聚对苯二甲酸乙二醇酯（PET）进行改性，静电纺丝法制备了 PET/PVA纳米纤维复合膜，并采用戊二醛蒸气对其交联处理，通过扫描电子显微镜（SEM）观察了纤维形貌，通过热分析（DSC）、水接触角测试及拉伸测试，考察了制品的性能。结果表明，成功制备了力学性能良好、亲水性优异的纳米纤维复合膜。
