Abstract
Layered organic/inorganic nanocomposites have been widely investigated in recent years. In this work, for the first time, the authors prepared laminated hydroxyapatite (HAp)/poly(methyl metacrylate) (PMMA) nanocomposites via one-step intercalative bulk polymerization. X-ray diffraction (XRD) and scanning electron microscopy (SEM) results revealed that different morphologies of PMMA/HAp nanocomposites were obtained by varying HAp contents. Differential scanning calorimetry (DSC) and tensile strength analysis indicated that both thermal stability and tensile strength were enhanced with incorporation of laminated HAp. The results reported here can be expanded to other HAp polymer systems, thus paving a new way of designing and fabricating biomimetic nanocomposites for biomedical applications.
