高角蛋白含量的角蛋白/PEO纳米纤维的制备及其性能表征
Fabrication and properties of high-content keratin/poly(ethylene oxide) blend nanofibers
摘要
Abstract
To prepare uncrosslinked high-content keratin/PEO nanofibers with water as solvent, human hair keratin was ex-tracted by 2-mercaptoethanol/urea/sodium dodecyl sulfate mixed system and blended with polyethylene oxide (PEO) with different mass ratios, and then keratin/PEO nanofibers were prepared by electrospinning. The results showed that the human hair keratin solution extracted with mercaptoethanol as reducing agent has higher viscosi-ty, which can significantly improve the spinnability of high proportion keratin/PEO blended spinning solution. The maximum mass ratio of keratin/PEO can reach 80/20 without crosslinking modification. With the increase of keratin content, the average diameter of nanofibres decreased and the diameter distribution became narrower. The average diameter of nanofibers decreased from 310 nm (keratin/PEO=30/70) to 82 nm (keratin/PEO=90/10). In the blended nanofiber spectrum, the absorption peak intensity of keratin in the amide I band, amideⅡband and amideⅢband increased gradually, and the absorption peak intensity of PEO at 1 092.86 cm-1 decreased gradually. The absorption peaks of PEO at 960 cm-1 and 841 cm-1 disappeared when the keratin content reached 80%. PEO could break the self-assembled structure of keratin to form a more stable secondary structure, thereby improving the thermal properties of blended nanofibers.关键词
