The effects of carbonaceous materials, such as graphene and carbon nanotubes, on tissue engineering have been thoroughly studied. However, difficulties in manipulating pure carbon materials into 3D scaffolds have hindered their applications in tissue engineering. Carbonization of polyacrylonitrile structure could be a potential alternative, as carbonized polyacrylonitrile (cPAN) possesses graphitic surface and can be processed into 3D structure. In this research, micro-porous 3D cPAN scaffolds were fabricated via freeze-drying and the overall mechanical, chemical properties of the scaffolds, with osteogenic functionalities, were characterized. These results indicate that 3D cPAN scaffolds can be applied as synthetic bone graft. |
