The morphology and mechanical property of polyacrylonitrile (PAN) fibers prepared in different gel coagulation baths were investigated using dry-jet gel-spinning technique,which could not only produce routine fibers with smooth surface but also ones with tuning parallel grooved surface.It indicated that the variety,temperature and constitute of gel coagulation bath all could significantly influence fiber surface morphology and its mechanical property.Compared with ethanol bath,higher mechanical properties of PAN fibers could be obtained in methanol due to higher draw radios.Because it combined advantages of dry-jet spinning and gel spinning,dry-jet gel-spinning technique held a huge potential to produce high performance carbon fibers efficiently.
