Abstract
Abstract: In order to improve the interface bonding performance of collagen-hydroxyapatite composite materials, gum arabic was introduced into the system, using Ca(NO3)2¡¤4H2O, (NH4)2HPO4, acid-soluble collagen, and gum arabic as raw materials, in situ A collagen-hydroxyapatite/gum arabic composite material was synthesized. FT-IR, XRD, and SEM were used to characterize the crystal phase structure, chemical composition, and micromorphology of the material, and the effect of gum arabic on the structure of the collagen-hydroxyapatite composite material was studied. The results show that gum arabic changes the interface morphology and structure of collagen-hydroxyapatite composite materials; as the gum arabic content increases, the grains of collagen-hydroxyapatite composite materials become smaller and the crystallinity decreases. ; The water absorption performance and in vitro enzymatic degradation ability of the composite material were significantly reduced (P<0.01), and its mechanical properties were improved within a certain range. A protein-polysaccharide complex may be formed between gum arabic and collagen or collagen-hydroxyapatite substances, thus playing a cross-linking role.
