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900~650 cm~(-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2.0%时,纳米纤维膜的最大强力和最大伸长都得到了显著增加。
In order to study the performance of electrospun two-piece vinegar (CA) / triclosan nanofibers, pure CA nanofibers and mixed CA / triclosan nanofibers were prepared by electrospinning method. Scanning electron microscopy (SEM) Fourier transform infrared spectrometer and universal strength tester to test the morphology, surface chemical properties and mechanical properties of nanofibers. The results showed that the addition of triclosan effectively reduced the beaded fibers on the surface of CA / triclosan nanofibers, and the fiber diameter distribution was more uniform. The mixed CA / triclosan nanofibers not only showed the characteristic absorption peak of CA , But also shows the flexural vibrational peak of benzene ring in triclosan in the range of 900-650 cm -1; the addition of triclosan effectively increases the maximum elongation of CA / triclosan nanofiber membrane, especially When the triclosan content of 1.5% and 2.0%, the maximum strength and maximum elongation of the nanofiber membranes have been significantly increased.
