摘要:
以六氟异丙醇(HFIP)溶解再生丝素膜,通过湿法纺丝获得再生丝素纤维。再生丝素纤维经1-(3-二甲基氨基丙基)-3-乙基碳化二亚胺(EDC)和N-羟基丁二酰亚胺(NHS)作为交联剂进行后处理,利用扫描电镜(SEM)、红外光谱(FTIR)、X-射线衍射(XRD)、DSC热分析法、力学性能等表征方法研究和分析了牵伸和交联前后纤维聚集态结构和力学性能的变化。研究结果表明:再生丝素纤维经牵伸和EDC/NHS交联改性后,纤维直径变细为87 μm,纤维内部结构以silk II结构为主;纤维的热稳定性提高,热分解峰峰值由281 ℃提高至288 ℃;纤维的断裂强度和断裂伸长率明显增大,分别达到1.41 cN/dtex和11.38%,表现出良好的柔韧性。
Abstract:
Regenerated silk fibroin fibers were prepared by the wet-spinning method with Hexafluoroisopropanol (HFIP) as the solvent. Then, the regenerated silk fibroin fibers were processed by 1-(3-Dimethylaminopropyl)- 3-ethylcarbodiimide(EDC) and N-Hydroxy succinimide(NHS) as the cross-linking agents. The fiber aggregative state structure and the changes of the mechanical properties before and after drafting and cross-linking were studied by scanning electron microscopy (SEM), X-ray diffraction (XRD), FTIR, DSC, the mechanical property and other indicative methods. The results showed that after drafting and EDC/NHS cross-linking, the average diameter of the regenerated silk fibroin fibers became fine and its average value equaled 87μm. The crystal structure was mainly in silk II structure. The thermal stability of the fiber was improved, and the thermal decomposition peaks shifted from 281 ℃ to 288 ℃. In addition, the mechanical properties of the fibers obviously increased. Its tensile strength and elongation at break reached 1.41 cN/dtex and 11.38%, respectively, exhibiting good flexibility.
