Novel Nanostructured Na⁺, Cu²⁺(Zn²⁺),CO₃²⁻‐HAP/Alginate Composite Scaffold: Fabrication, Characterization and Mechanical Properties

Abstract

The aim of this study was to prepare and characterize the novel Alginate (Alg)/Na+,Cu2+(Zn2+),CO32−‐containing apatite nanocomposite scaffolds, as well as to investigate their mechanical characteristics. During first stage, synthesized Na+,CO32− ‐ containing apatite‐type calcium phosphate was used as initial matrix for sorption of Cu2+ and Zn2+ from solutions with different molar concentrations. Then, the prepared Na+,Cu2+/Zn2+,CO32− ‐ containing apatite was used for creation of Alg/phosphate composites and their mechanical properties were evaluated. Results showed that all samples have a high Young's modulus ((370‐747) MPa), and their compressive strength is in the range of (233‐255) MPa. All Alg/phosphate composites are characterized by large plastic deformation when compressed.
