中文摘要：

为研究静电纺二醋片（CA）／三氯生纳米纤维的性能，利用静电纺丝方法制备了纯CA纳米纤维和混合CA／三氯生纳米纤维，并利用扫描电子显微镜（SEM）、傅里叶红外光谱仪和万能强力仪测试了纳米纤维的形貌特征、表面化学性能和机械性能。结果表明：三氯生的加入有效地减少了CA／三氯生混合纳米纤维表面的串珠纤维，且纤维直径分布更均匀；混合的CA／三氯生纳米纤维不仅表现出了CA的特征吸收峰，还在900～650cm^-1范围内显示出了三氯生中苯环的弯曲振动峰；三氯生的加入有效增加了CA／三氯生纳米纤维膜的最大伸长，特别是当三氯生含量为1．5％和2．O％时，纳米纤维膜的最大强力和最大伸长都得到了显著增加。

英文摘要：

To study the performance of electrospun cellulose acetate（CA）/triclosan nanofibers, the pure CA nanofibers and mixed CA/ triclosan nanofibers are prepared through electrospinning method. The morphologies, chemical properties and tensile properties of CA/ triclosan nanofiber are carried out by using scanning electron microscopy （ SEM）, Fourier infrared spectrometer, and universal electronic strength tester. The results show that the addition of triclosan decreases the beaded nanofibers and diameter deviation of CA/triclosan nanofibers effectively. The fibers are more evenly distributed. The mixed CA/triclosan nanofibers not only expresses the characteristic peaks of CA, but also expresses the bending vibration peak of triclosan in 900-650 cm^-1. The addition of triclosan increases the maximum breaking elongation of CA/triclosan nanofibers, especially when the content of triclosan is 1.5% and 2.0%, the maximum breaking strength and breaking elongation of CA/triclosan nanofibers have been improved greatly.
