Outline of Final Research Achievements

High strength polyacrylonitrile (PAN) fibers with tensile strength of over 2 GPa were prepared by wet spinning using a good recyclable ionic liquid, 1-buthyl-3-methylimidazolium chloride, as a solvent. High strength fiber with the highest average tensile strength of 2.3 GPa was successfully obtained by use of high molecular weight resin and optimization of spinning and secondary drawing conditions. The stress during tensile measurement was enhanced with increase of secondary drawing ratio owing to raise of degree of molecular orientation, but initial modulus and elongation at break were barely changed regardless of the draw ratio. In especial, for highly drawn fibers, the elongation at break was almost constant at ca. 12 %. This value was considerably large for high strength fiber, which means that the PAN fibers in this study had high toughness. This was a very unique character among high strength fibers.
