Graphene-bioactive glass composites: Structural, Vickers hardness, and gamma-ray attenuation characteristics

Introduction: Graphene-based materials have gained increasing attention for use in radiation attenuation applications. In this study, pristine graphene nanoplatelet-containing (1, 3, 5, and 10 wt%) borate-based bioactive glass composites were prepared. Methods: Structural properties, Vickers microhardness, gamma-ray shielding properties of the fabricated examined detail. Results Discussion: revealed that inclusion matrix led to a decrease bulk density glass-based from 2.41 2.31 g/cm 3 . Similarly, hardness was obtained as concentration increased due convoluted effect non-uniform distribution nanoplatelets higher residual porosity. bare wt% graphene-containing discs measured be 5.03 ± 0.28 GPa 1.87 0.56 GPa, respectively. On other hand, incorporation starting decreased crack propagation after indentation which may attributed an increase fracture toughness. fundamental gamma ray absorption glasses 0.015–15 MeV incident photon energy range. For purpose, Py-MLBUF code employed determine parameters. showed linear coefficients samples. incorporated into structure, exposure buildup factor values increased. The growing ratio structure contributed negatively photon’s tendency interact with material.
