Fabrication of bioactive glass 58S/chitosan/zeolite 13X biocomposite using liquid phase method

In this paper, a biocomposite was prepared by liquid phase method using 58S bioactive glass, high molecular weight chitosan and 13X zeolite. Physical characterization of the sample was performed using FT-IR, XRD, FE-SEM and EDX analysis. Results of FT-IR showed the presence of bands related to each component. Also, a comparison between FT-IR spectrum and XRD pattern of chitosan with the ones of prepared composite confirms the cross-linking of chitosan. The compressive strength of the sample was determined using the stress-strain diagram. According to this test, the compressive strength of the sample is 51.43 MPa. Also, the bioactivity of the biocomposite was studied in the simulated body fluid (SBF) at 37 ° C for 3 days, which showed a favorable bioactivity. The XRD pattern and FE-SEM images of the biocomposite before and after immersion in SBF solution show the growth of apatite on the biocomposite. The EDX spectrum also confirms the presence of all components. According to the previous studies, the composite prepared in this paper has more desirable properties than similar composites.
