Abstract

Abstract: The Ca10 (PO4 )6 (OH)2 /Li-BioMOFs resin nanocomposites were prepared and introduced as a new dental resin nanocomposite. Ca10 (PO4 )6 (OH)2 /Li-BioMOFs resin nanocomposites were synthesized with individual mechanical properties in the presence of lecithin as a biostabilizer. The hydrothermal synthesis of hydroxyapatite (HAp) nanostructures occurred in the presence of Glycyrrhiza glabra (liquorice) root juice that acts not only as a green capping agent but also as a reductant compound with a high steric hindrance agent. Results showed that the mechanical properties of nano-Ca10 (PO4 )6 (OH)2 structures with a concentration of 60 ppm Li-BioMOF were increased by ∼132.5 MPa and 11.5 GPa for the flexural and Young's modulus, respectively. Based on the optical absorption ultraviolet-visible spectrum, the HAp nanocrystallites had a direct bandgap energy of 4.2 eV. The structural, morphological, and mechanical properties of the as-prepared nanoparticles were characterized with the FT-IR (Fourier-transform infra-red), UV-Vis (ultraviolet visible) spectrums, X-ray diffraction, SEM (scanning electron microscopy), and TEM (transmission electron microscopy) images, and atomic force microscopy (AFM). It is suggested that HAp structures loaded on the Li-BioMOFs are as a suitable and novel substrate which can be considered as a promising biomaterial in dental resin nanocomposites significantly improved the strength and modulus. Graphical abstract: Highlight: For the first time Ca10 (PO4 )6 (OH)2 /Li-MOFs were synthesised as dental resin nanocomposites with hydrothermal approach. Glycyrrhiza glabra (Liquorice) root juice acts not only as green capping agent but also act as reducing agent. Li-BioMOFsasa suitable substrate improve the hydroxyapatite mechanical properties. Li-BioMOFssubstrates for Ca10 (PO4 )6 (OH)2 nanostructures were synthesised in the presence of lecithin as bio stabiliser.
