In this research, TiO2 nanopowders were synthesized by hydrothermal method. For the synthesis of TiO2-CH and TiO2-PVA nanocomposites, titanium dioxide nanopowders were combined with chitosan and PVA polymers by sol-gel method. The coating of the implant surfaces was done by dip-coating method. Nanopowders and implants coated with nanomaterials were characterized by X-ray diffraction, FESEM, EDX, FTIR, BET, stress-strain and adhesion. The XRD spectrum shows the formation of the anatase phase of TiO2 nanopowders without any additional peaks, and peaks related to chitosan and PVA are also seen in the diffraction spectrum. According to the BET results, it was found that all three nanocomposites have large and macro-sized pores. In the presence of chitosan, the largest pore diameter is observed and in the presence of PVA, the smallest pore diameter is observed. Considering that the average diameter of the porosity in the TiO2-CH sample is 85.304 micrometers, and mechanically it has the most flexibility and adhesion to the substrate. Therefore, compared to the other two samples, it seems to be a more suitable option for scaffold design in the field of bone tissue engineering.
