초록
Biomimetic hydroxyapatite deposition method has been used to prepare hybrids and composites. We attempted to coat hydroxyapatite layer on cordierite through a biomimetic process for fabrication of a novel functional material. The cordierite treated with calcium chloride solution was evaluated on hydroxyapatite formation in a simulated body fluid (SBF). The cordierite was hydrated by treating with calcium chloride solution, which led to the formation of silanol (Si-OH) groups on its surface. The 0.25 mol • dm−3 calcium treated cordierite formed hydroxyapatite on its surface after soaking in SBF within 7 d while the controls, slide glass and alumina plate also treated with the calcium chloride solution, did not show any change in their surface morphology before and after soaking in SBF. This processing might be available for the hybridization of hydroxyapatite and silica-based materials.
