| 摘 要： | 选取二甲亚砜(DMSO)作聚醚砜(PES)与聚乙烯醇(PVA)混合体系的溶剂,采用静电纺丝法制备了PES/PVA复合超细纤维,再用水抽提去除纤维中的PVA组分,成功地获得了PES基多孔超细纤维。运用扫描电镜(SEM)、透射电镜(TEM)、原子力显微镜(AFM)等表征手法观测研究了不同PVA含量时纤维及孔洞的形貌。

Preparation and Morphology of the PES-Based Porous Ultrafine Fibers |
| |
| Abstract: | The poly(ether sulfone)(PES) and poly(vinyl alcohol)(PVA) composite ultrafine fibers were obtained by the technique of electrospinning from the various weight ratios PES/PVA mixture dissolving in the dimethyl sulfoxide(DMSO).The PVA component was removed by water extraction so that the PES-based porous fibers were manufactured.Scanning electron microscope(SEM) and transmission electron microscope(TEM) were employed to study the morphologies of the porous fibers,while most notably the atom force microscope(A... |
