It is well-known that LiCl/N,N-dimethylacetamide solvent is a good medium for dissolution of cellulose. In this article, cellulose/hydroxyapatite (HA) nanocomposites were carried out using microcrystalline cellulose, CaCl2, and NaH2PO4 via microwave-assisted method. The cellulose solution was previously prepared by the dissolution of microcrystalline cellulose in LiCl/N,N-dimethylacetamide solvent. The cellulose/HA nanocomposites were characterized by X-ray powder diffraction (XRD), Fourier transform infrared spectrometry (FTIR), and scanning electron microscopy (SEM). We also investigated the effects of heating times, heating temperatures, and the reactant concentrations on the phases, microstructures, and morphologies of the cellulose/HA nanocomposites. This microwave-assisted method has advantages of being simple, rapid, low-cost, and environmentally friendly. The cellulose/HA nanocomposites could be a candidate for the biomedical applications.

Keywords:Nanocomposites; Hydroxyapatite; Cellulose; Microwave; LiCl/N,N-dimethylacetamide
