XPS studies of Hydroxyapatite Powders by Grafting Octadecyltrichlorosilane


Article Preview

It is known that the organic molecules can provide effective means to tailor the surface properties of the biodegradable ceramic. In this paper, a long-chain organic silane- Octadecyltrichlorosilane(OTS) was used as coupling agent and hydroxyapatite(HA) was the candidate ceramic. Samples were characterized by means of XPS technique. XPS results indicated that Si-O-P bond was formed on the HA surface after surface-modification, which means OTS was grafted onto the HA surface through covalent bond , XPS results also showed that by regulating the surface-modification process Si(Atomic percentage) content on HA surface could be changed from 0 to 2.88%.
