摘要
A new kind of tissue engineering scaffold materials of nano-apatite （ NA ） and polyamide6 （ PA6 ） biocomposite was prepared by means of the co-solution method. The NA crystals uniforndy distribute in the composite with a size of 10-30 nm in diameter by 50-90 nm in length. The NA/ PA6 composite has good homogeneity and high NA content, and excellent mechanical properties close to those of natural bone. The porous 3-D scaffold has not only macropores, but also micropores on the walls of macropores with porosity of about 80% and the size of pore diameter of about 300μm made by injection foam. The biocomposite can be used for bone repair and as scaffolds in tissue engineering.
