摘要
在胶原蛋白与聚乙烯醇（PVA）复合后的溶液中加入少量质量分数为0.05％-0.25％的碳纳米管，通过湿法纺丝制得PVA／胶原蛋白／碳纳米管复合纤维，研究了复合纤维的结构和性能。结果表明：碳纳米管与PVA和胶原蛋白有较好的相容性，在复合纤维中分散比较均匀。添加质量分数为0.25％碳纳米管时，复合纤维结晶度提高了37.62％，水中软化点提高了5℃，回潮率从11.50％下降到10.83％；加入质量分数为0.05％的碳纳米管时，复合纤维的断裂强度提高57.07％。
Polyvinyl alcohol （PVA）/collagen/carbon nanotubes composite fiber was prepared from the composite solution of collagen and PVA incorporated with 0.05% -0.25% carbon nanotubes by mass fraction via wet spinning process. The structure and properties of the composite fiber were studied. The results showed that the carbon nanotubos had a fairly good compatibility with PVA and collagen and a uniform dispersion in the composite fiber. The crystallinity of the composite fiber was increased by 37.62% and the softening point in water by 5℃ and the moisture regain was decreased from 11.50% to 10.83% as the carbon nanotubes content was 0.25% by mass fraction. The breaking strength was increased by 57.07% as the carbon nanotubes content was 0.05% by mass fraction.
