胶原蛋白涂覆棉纤维的研究

Study of cotton fiber coated by collagen

胶原蛋白具有独特的3股螺旋结构,优越的生物相容性和生物降解性,极具应用前景。为了进一步拓展纤维素的应用领域和开发新型绿色纤维素纤维,采用高碘酸钠对棉纤维进行局部有限选择性氧化,然后与胶原蛋白溶液反应,制备了涂覆胶原蛋白棉纤维。结果表明:经高碘酸钠有限氧化后棉纤维的断裂强度降低不明显;胶原蛋白分子通过席夫碱C N双键共价结合在棉纤维表面。

Collagen has great potential applications because of its unique construction of three-ply helix, predominant bio-compatibility and bio-degradability. For further development of the application domain of cellulose and exploiting new green cellulosic fibers, a new cotton fiber coated with collagen was prepared by the limited selective oxidation of the fiber with sodium periodate and subsequent treatment with the solution of collagen in this paper. The results showed that the breaking strength of the cotton fiber after the limited oxidation by sodium periodate did not decrease remarkably, and the collagen molecules through the C =N double bond of the Schiff base combined on the surface of the cotton fiber.
