英文摘要	Ultra-high molecular weight polyethylene ( UHMWPE)/chitin nanocrystal ( CNC) fibers were prepared. Compared with the pure UHMWPE fibers, the ultimate tensile strength and Young's modulus of UHMWPE/CNC fibers are improved by 15.7% and 49.6%, respectively, with the addition of chitin nanocrystals ( CNCs) of 1 wt%. The melting temperature ( T-m) of UHMWPE/CNC fibers was higher than that of pure UHMWPE fibers. Pure UHMWPE fibers and UHMWPE/CNC fibers were characterized with respect to crystallinity, orientation and kebab structure by wide-angle X-ray diffraction ( WAXD), small-angle X-ray scattering ( SAXS) and scanning electron microscopy ( SEM). It is found that the CNCs act as the shish structure in UHMWPE/CNC fibers and the kebab crystals are grown around the CNCs. There was almost no difference between pure UHMWPE fibers and UHMWPE/CNC fibers in orientation. But the degree of crystallinity of various stages of UHMWPE/CNC fibers was respectively higher than the corresponding stage of pure UHMWPE fibers. Moreover, the addition of 1 wt% CNCs improved the thickness of kebab crystals and accelerated the transformation of kebab to shish.
