“…22 Broad peaks around 3370, 2903, 1056, and 610 cm −1 were also found in studies reported elsewhere, indicating the presence of microcrystalline cellulose type I. 5,13 The reduction of the 3335 cm −1 band with the increasing Hap content, particularly for G5 group, indicate strong interactions of OH groups of cellulose and Hap. Similar behavior was observed for the band at 1025 cm −1 , which became broader with the increasing of Hap.…”

“…[1][2][3] Hydroxyapatite (Hap) is the major component of bones and is being continuously used as biomaterial in tissue engineering, mainly due to its high bioactivity and good osteoconductivity. [4][5][6] Thus, Hap particles can be uniformly dispersed in cellulose matrix, creating high quality biocompatible inorganic-organic hybrid films. 7 The synthesis of Hap is normally based on dry methods, including solid state and mechanochemical method; wet methods such as sol gel, hydrothermal, hydrolysis, emulsion, or chemical precipitation; or high temperatures processes, including pyrolysis and combustion.…”

A new biofilm of cellulose coated with hydroxyapatite particles have been prepared using a simple, fast and low temperature process based on a microwave-assisted hydrothermal synthesis. The cellulose used as matrix of the biocomposite was extracted from banana stems residues. The hydroxyapatite coating was performed using calcium nitrate tetrahydrate, phosphoric acid, and 1,2-ethylenediamine dispersed in a cellulose/water solution, with posterior microwave-assisted hydrothermal synthesis, for 5 min at 140°C. The chemical, structural, thermal, and morphological properties of the composites were investigated by X-ray diffraction, infrared spectroscopy, thermogravimetry and field emission scanning electron microscopy. Results showed that the methodology was effective to produce high quality composites, with good thermal stability. Cell viability tests indicated that the cellulose/Hap films were not cytotoxic.
