Abstract:
n-HA /PVA com posite hydrogel is prepared by in situ preparation. By controlling the content o f PVA, n- HA and water, composite hydroge ls w ith d ifferent proportion w ere prepared. TEM, IR, XRD and bu rning exper-i m en ts w ere emp loyed to characte rize the struc ture, com po sition and m echanical properties of them ater ia .l The results ind icated that the 3D structure of the PVA m olecu le a ffected the crystalline grow th of hydroxy apatite, certa in bond ing ex isted between HA and PVA, n-HA w as distr ibuted in the PVA m atrix un iform ly, and the concentration ofHA obv-i ously affected them echan ica l properties o f the composite hydrog el.
