| Résumé : |
The electrospinning method was applied to construct polyamide 6 (PA6) nano-cobweb fibrous membranes at various PA6 and barium chloride (BaCl2) concentrations. The surface morphologies of the membranes were observed by the scanning electron microscope (SEM), and the average nanofiber diameter, average nano-cobweb diameter and coverage rate of nano-cobweb were calculated. The results show that the nano-cobweb membrane is composed of conventional electrospun fibers and ultrafine spider-web-like nano-cobwebs. With the increasing of PA6 concentration, the average diameters of the nanofiber and the nano-cobweb both in-crease, whereas the nano-cobweb coverage rate is high at a moderate PA 6 concentration. With the increasing of BaCl2 concentration, the nanofiber diameters become larger but the nano-cobweb diameters barely change. The nano-cobweb coverage rate increases initially and then decreases. |
