Abstract:Polyacrylonitrile (PAN)‐based precursor fibers with different mechanical properties prepared by wet‐spinning and its correlation with microstructure was researched, the primary structural factors that affecting its properties were analyzed. The tensile strength and modulus of precursor fibers increased from 4.63 cN/dtex to 9.16 cN/dtex and 99.09 cN/dtex to 168.92 cN/dtex, respectively, with the increase in crystallinity from 69.29% to 87.84% and orientation degree increased from 83.95% to 93.81%, high performa… Show more
