纳米炭黑填充的Lyocell纤维的结构与性能

Structure and properties of nano-carbon black filled Lyocell fiber

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。

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 cellulose Ⅱ crystal 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.
