The use of graphene-based nanomaterials in tissue engineering has shown immense potential in improving the microstructure of polymeric blends. The addition of graphene nanoscrolls (GNS) to polycaprolactone (PCL) and chitosan (CHT) scaffolds and the subsequent improvements in physical properties, crystallinity, and degradation rate are indeed promising. The use of techniques like DSC (differential scanning calorimetry) and XRD (x-ray diffraction) to characterize thermal behavior and crystal state provides valuable insights into the material properties. FTIR spectroscopy demonstrated the changes in the chemical structure of the polymer blend during degradation, while nanoindentation was used to study the mechanical properties of the scaffolds. The SEM (scanning electron microscopy) images offering a closer look at the surface morphology and microstructure further contribute to a comprehensive understanding of the scaffold's characteristics. The enhanced crystallinity and lower degradation rate, coupled with a well-defined interconnected pore structure, suggest that the integration of graphene nanoscrolls at a concentration of 0.1 wt.% is a beneficial approach. This not only improves the material properties but also creates an optimal environment for potential tissue engineering applications, particularly for load-bearing tissues.
