23 Jul Method for mineralizing silk fiber
Abstract
The invention discloses a method for mineralizing silk fiber. The method comprises the steps of adding stearyl amine into a mixed solution of linoleic acid and ethyl alcohol, stirring the mixed solution until the mixed solution is dissolved completely, adding a Ca(NO[3])[2] aqueous solution, standing the solution until the solution is layered, and adding a Na[3]PO[4] aqueous solution and stirring; adding the silk fiber, making the silk fiber is immersed by the solution, and heating the solution at a high temperature; taking out the silk fiber, washing the silk fiber with ethyl alcohol, removing the uncombined elements on the surface of the silk fiber, and achieving the mineralization of the silk fiber. According to the method, the superiority supplementary between the silk fiber and hydroxyapatite is achieved, on the basis of keeping the hydroxyapatite as bone tissue engineering materials, the mechanical properties of materials are improved, and the silk fiber/hydroxyapatite composite materials are biological materials of great properties and can be applied to bone tissue engineering widely.
