The invention relates to a method for preparing a
polycaprolactone-
keratin composite nanometer
fiber pipe. The method includes the steps of firstly, dissolving
polycaprolactone in a
solvent, stirring the
solvent to dissolve the
polycaprolactone, and obtaining a polycaprolactone solution; secondly, dissolving
keratin in a
solvent, stirring the solvent to dissolve the
keratin, and obtaining a keratin solution; thirdly, mixing the polycaprolactone solution with the keratin solution according to the
mass ratio of 95:5 to 5:95, stirring the mixture to mix the mixture evenly, and obtaining a
spinning solution; fourthly, conducting electrostatic
spinning, and obtaining the polycaprolactone-keratin composite nanometer
fiber pipe with a cylindrical collection roller serving as a
receiver. The tubular material obtained through the method not only keeps good
biological activity of the keratin, but also has good tenacity and
mechanical strength of the polycaprolactone; meanwhile, the tubular material has the advantages of being adjustable in inner
diameter, simple in preparation method and the like and is expected to be used for the field of artificial blood vessels and the like.
