摘要：
Hydroxyapatite/chitosan (HA/CS) nano-fibrous composites with HA contents of 0-80 wt% were prepared by in situ hybridization. The hydroxyapatite nano-fibers with average diameter of about 3 nm and length of 20-60 nm homogeneously disperse in the chitosan matrix. The compressive strength of these nano-fibrous HA/CS composites increase with the increasing HA content and reached the highest values of 178 MPa. The results of in vitro tests in simulated body fluid solutions indicate that the HA/CS bio-composites have good biodegradability and bioactivity. All the results suggested that the HA/CS bio-composites are appropriate to be applied as bone substitute in bone tissue engineering.
