摘　　要： 分别将不同掺量的环糊精(β-CD)与聚丙烯腈(PAN)共混,利用静电纺丝法制备CD-PAN复合纳米纤维膜。使用扫描电子显微镜(SEM)、傅里叶红外光谱分析仪(FTIR)对纳米纤维的表面形态及纤维分子结构进行表征,并通过微机控制电子万能试验机测试CDPAN纳米纤维膜的力学性能。结果表明,β-CD环糊精均匀的分布在纤维中,β-CD的加入,向复合纤维膜中引入了羟基等,为纤维膜吸附重金属离子提供了条件;随着β-CD含量的增加,复合纤维直径逐渐增大,纤维膜断裂强力也呈现增长趋势;且环糊精含量为8wt%时,纤维膜强力最大,为8.22N,而断裂伸长的变化无明显规律。 CD - PAN composite nanofibrous membranes were prepared by electrospinning with different content of cyclodextrin （β -CD） and polyacrylonitrile （PAN）. The surface morphology and the molecular structure of the nanofibers were characterized by scanning electron microscopy （SEM） and Fourier transform infrared spectroscopy （FTIR）. The mechanical properties of the CD -PAN nanofibers were tested by a computer controlled electronic universal testing mackine. The results show that β- CD cyclodextrin is uniformly distributed in the fiber and β - CD is added into the composite fiber membrane. The hydroxyl radicals are introduced into the composite fiber membrane, which provides the conditions for the adsorption of heavy metal ions. With the increase of β-CD content ,The fiber diameter increased gradually, and the breaking strength of the fiber membrane also showed an increasing trend. When the content of cyclodextrin was 8wt%, the strength of the fiber membrane was 8.22N, and the elongation did not change obviously.
