TY - JOUR TI - HIGHLY ALIGNED ELECTROSPUN NANOFIBERS BY HOT-DRAWING AU - Liu Hong-Ying AU - Xu Lan AU - Sun Qi-Long JN - Thermal Science PY - 2015 VL - 19 IS - 4 SP - 1357 EP - 1360 PT - Article AB - Aligned polyacrylonitrile nanofibers were prepared by a modified electrospinning. Hot-drawing was used to improve the properties of the obtained nanofibers. Experiment revealed great changes in degree of alignment, crystallization, exothermic peak, and mechanical properties of nanofibers.
