Vapour Diffusion Route to Mineralize Graphene and Polymer Surfaces with Calcium Phosphate Intended for Biomedical Applications

摘要

After successful application of the sitting drop vapour diffusion route to deposit calcium phosphate layers on mica muscovite sheets, in this work we have extended the method to mineralize polymer surfaces (OSTE+) and bidimensional materials (graphene), aimed to prepare implants or scaffolds for nonload bearing applications in the medical sector. Thin octacalcium phosphate/apatite layers have been deposited on mica muscovite sheets. Thin apatite/octacalcium phosphate layers deposited on OSTE+ polymer lames. When graphene nanoflakes where used as support, this technique yielded apatite/graphene nanocomposites.
