Establishing an Apatite Supramolecular Model with Fourier Transform Infrared Spectroscopy Assay——Apatite Supramolecular Model
Abstract: The fluoridated hydroxyapatite (FHA) was used to enhance the anti-carious effect of human tooth. Both the treatment method and the optimizing molar ratio were naturally the key of the sintering effect. In current studies, we have investigated the molecular characteristics and the sintering mechanism of sintered FHA composites based on HA-CaF2 system. The molecular characteristics of the FHA composites assayed by Fourier transform infrared spectros- copy (FT-IR) techniques. The FHA composites were prepared by sintering different combinations of HA and CaF2. FHA composites show the OH F HO and/or the OH F hydrogen absorption band under the FT-IR analysis. With grad- ual increase of CaF2 content, the sequence of FT-IR bands show OH F stretching mode vibration first, then followed by OH F HO liberational mode vibration and, finally, the OH F liberational mode vibration. Therefore, according to sintering theory and FT-IR analysis we established an apatite supramolecular model to provide molecular characteris- tic foundation for sintered FHA structure.
