Method for producing porous body comprising apatite/collagen composite fibers
View Patent ↗A method for producing a porous body comprising apatite/collagen composite fibers comprising the steps of gelling a dispersion comprising long apatite/collagen composite fibers having an average length of 10-75 mm, short apatite/collagen composite fibers having an average length of 0.05-1 mm, and a liquid; freezing and drying the resultant gel to form a porous body; and cross-linking collagen in the porous body.
1. A method for producing a porous body comprising apatite/collagen composite fibers comprising:
gelling a dispersion comprising long apatite/collagen composite fibers having an average length of 10-75 mm, wherein at least 90% by mass of the long apatite/collagen composite fibers has a length in the range of 5-100 mm, short apatite/collagen composite fibers having an average length of 0.05-1 mm, wherein at least 90% by mass of the short apatite/collagen composite fibers has a length in the range of 0.01-2 mm, and a liquid;
freezing and drying the resultant gel to form a porous body; and
cross-linking collagen in said porous body.
2. The method for producing a porous body comprising apatite/collagen composite fibers according to claim 1 , wherein a binder is not added to said dispersion.
3. The method for producing a porous body comprising apatite/collagen composite fibers according to claim 1 , wherein the ratio of said long fibers to said short fibers is 0.2-0.8 in said dispersion.
4. The method for producing a porous body comprising apatite/collagen composite fibers according to claim 2 , wherein the ratio of said long fibers to said short fibers is 0.2-0.8 in said dispersion.
