| 摘要: |
Polyacrylonitrile nascent fibers were prepared via the wet-spinning
technique and a dimethyl sulphoxide/H2O coagulation bath system was adopted. The
objective of this study was to investigate the influence of dope extrusion rates on
formation and characterization of nascent fibers. Nine different dope extrusion rates
were adopted when other technique parameters were kept steady. The surface morphology
of nascent fibers was observed by field emission scanning electron
microscopy. The results showed that the dope extrusion rates played significant effects
on the cross-section structure, surface morphology, degree of crystallization, and sound
velocity of the nascent fibers. With an increase of dope extrusion rate, the surface
roughness increased, and the sound velocity had a point of inflexion. Moreover, the
degree of crystallization had a maximumwhen the dope extrusion rate was 5.92 m/min. |
