Synthesis and characterization of banana peel derived biopolymer/hydroxyapatite nanocomposite for biomedical applications

The aim of this study is to prepare and characterize the novel green biopolymer/HAP nanocomposite. In this synthesis process the biopolymer derived from the peel of bananas with different concentrations were used for the synthesis of HAP nanocomposites. Fourier transform infrared spectroscopy (FTIR), X-ray diffraction analysis (XRD), scanning electron microscope (SEM) and transmission electron microscope (TEM) were used to identify the functional groups, phase structure and morphology of the as-synthesized composite. FTIR analysis confirms the COO - ….Ca 2+ interaction between the as-prepared biopolymer and HAP. The nanocomposite crystal behavior and phase analysis using XRD analysis shows the formation of phase pure nanocomposite with low crystalline nature. The morphology of the as-synthesized sample was investigated using SEM and TEM analysis which demonstrates the presence of discrete particles with reduced size. Hence, the as-synthesized nanocomposite could have a potential application in the various biomedical fields.
