Morphology of apatite formed on polyamide films in a solution mimicking body fluid

Abstract

To fabricate apatite-polymer hybrids with structures similar to bone tissues, it is important to use a process where bone-like apatite is formed on polymer surface in a body environment. We previously found that apatite could be deposited on the surfaces of aromatic polyamide films containing carboxyl or sulfonic group in a solution mimicking extracellular fluid. In this study, morphology of the apatite formed on the polyamide films containing carboxyl group was examined. Aggregations of minute flakey particles were observed, and the particles formed complex conjunctures at the interface between the apatite layer and polymer surface.
