| Popis: | In this study, the jet formation progress, jet motion, resultant fiber diameter, fiber mat morphology, inner structures and mechanical properties of the fibers prepared at different heating temperatures via melt electrospinning system were studied, in a comprehensive and systematic manner. The temperature distribution of the melt electrospinning configuration was simulated, in order to provide a good deal of insight into the experimental results. High-speed photography was adopted to capture the images of jet formation process and jet motion during melt electrospinning. The experimental results showed that higher heating temperature at the spinneret results in shorter jet formation time, smaller fiber diameter, more disordered fiber mat, lower degree of crystallinity and strength. The simulation works was carried out, aimed at facilitating to deeply understand the experimental results. |
