The crystalline structure of n-HA was studied by means of Rietveld method. A series of structure parameters, such as, cell lattice parameters (a or c), bonding lengths and a numerical index of distortion for PO4 tetrahedron, were calculated by Newton-Raphson calculating method to characterize the crystalline structure of HA at atom level. The results showed that n-HA was mainly linked with KGM and CS by hydrogen bonding between OH−-PO 4 3− of n-HA and -C=O, -NH of KGM-CS copolymer, and there was a stable interface formed between the three phases in the composite. Besides, orientation of this hydrogen bonding resulted in the decrease of the relative crystallization degree of KGM-CS copolymer.
