摘　　要：将炭黑水悬浮溶液与粘胶原液共混制得不同添加比例的纺丝溶液,通过湿法纺丝制备炭黑复合粘胶纤维。采用扫描电镜(SEM)、广角X射线衍射仪(WAXD)及纤度强度仪等分析所制备纤维的结构与性能。WAXD分析结果表明,不同添加比例炭黑的复合纤维均为纤维素Ⅱ型晶体结构,结晶度随着炭黑添加量的增加逐渐降低;SEM结果显示,不同添加比例的炭黑在粘胶基体中的分布都较均匀,没有明显团聚现象,但是随着添加量的增加,纤维的孔隙增大增多,光滑性下降,但纤维仍然保持锯齿截面形状;对纤维力学性能分析结果表明,添加适量的炭黑可使复合纤维素纤维力学性能提高,而添加过量时,力学性能反而降低。Spinning solutions with different addition ratios were prepared by blending carbon black aqueous suspension with cellulose solution. The viscose/carbon black composite cellulose fibers were prepared by wet spinning. The structure and properties of the prepared fibers were analyzed by scanning electron microscopy （SEM）, X-ray diffraction （WAXD） and intensity analyzer. WAXD analysis results showed that the composite fibers with different proportion of carbon black still have the cellulose Ⅱ crystal structure, the degree of crystallinity decreases with the addition of carbon black; The results of SEM showed that the appropriate proportion of carbon black in the composite fiber was distributed uniformly in the matrix of the viscose, and there was no obvious agglomeration. The results of fiber mechanical properties analysis showed that the mechanical properties of the composite cellulose fibers increased with the addition of the appropriate amount of carbon black, while the mechanical properties of the composite cellulose fibers increased when the excess amount of carbon black was added.
