Structure And Properties Of Animal Silk/SWNTs Composite Nanofiber

In this paper, animal silk and SWNTs were used as raw materials, animal silk/SWNTs composite nanofibers, animal silk/Baiyao composite nanofibers and animal silk/SWNTs/Baiyao composite nanofibers were obtained by electrospinning. The main contents of this paper include the structure and physical properties of the fibers, and their biocompatibility, the details were as follow:The structure and physical properties of fiber mats:The effects of SWNTs and Baiyao on the morphology, crystallinity degree and physical properties of composite fibers were discussed. The results indicated that with the addition of SWNTs, the morphology and mechnial properties did not change; Baiyao enlarged the fiber diameter and enhanced the mechanical property of the electrospun fibers.The mechnial properties, moisture absorption and oxygen transmission conformed the needs of haemostatic dressings.Biocompatibility and hemostatic property:The attachment, spreading, proliferation and morphology of L929cell on animal silk/SWNTs composite nanofiber mat, animal silk/Baiyao composite nanofiber mat and animal silk/SWNTs/Baiyao composite nanofiber mat were observed. The results showed that the proliferation and morphology of cells on the fiber mats were very well.The process of the simulated plasma permeating into the mats with diffient contents was shooted, the results demonstrated the hemostatic property of animal silk/SWNTs/Baiyao composite nanofiber mat was best, the animal silk/Baiyao composite nanofiber mat was second and the animal silk/SWNTs composite nanofiber mat was worest. The SWNTs and Baiyao both had more effects on the hemostatic property than the animal silk mat.
