| 摘 要： | 研究了纳米炭黑在Lyocell纺丝溶液中的分散性,制备不同含量纳米炭黑填充的Lyocell纤维,分析了纤维的结构与性能。结果表明:纳米炭黑在Lyocell纺丝溶液中具有良好的分散性;所得的纤维仍然具有纤维素Ⅱ晶型的结构,同时还保留了纳米炭黑的特征衍射峰;填充了纳米炭黑的纤维力学性能略有降低,但热稳定性不变;SEM结果表明纳米炭黑填充的Lyocell纤维表面光滑且截面为圆形,结构更加致密。

| Abstract: | The dispersity of nano-carbon black in Lyocell spinning solution was studied. The Lyocell fibers filled with different amounts of nano-carbon black were prepared. The structure and properties of the obtained fiber were analyzed. The results showed that the nano-carbon black can be dispersed very well in Lyocell spinning solution. The obtained fibers had celluloseⅡcrystal structure and kept the characteristic peak of carbon black at the same time. The mechanical properties of nano-carbon black filled Lyocell fiber decreased slightly but the heat stability remained unchanged. The SEM results showed that the nano-carbon black filled Lyocell fiber had a smooth surface and circular cross section with a compacter structure. |
