摘要：
Electrospun fiber has highly structural similarity with natural bone extracelluar mairix ECM). Many researches about fabricating organic inorganic composite materials have been carried out in order to mimic the natural composition of bone and enhance the biocompatibility of materials. In this work, pearl powder was added to the poly (3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBV) and the composite nanoriber scaffold was prepared by electrospinning. Mineralization ability of the composite scaffolds can be evaluated by analyzing hydroxyapatite (HA) formation on the surface of nanoliber scaffolds. The obtained composite nanoliber scaffolds showed an enhanced mineralization capacity due to incorporation of pearl powder. The HA fonued amount of the composite scaffolds was raised as the increase of pearl powder in composite scaffolds. Therefore, the prepared PHBV/pearl composite nanofiber scaffolds would be a promising candidate as an osteoconductive composite material for bone repairing.
