Three-dimensional (3D) porous graphene oxide/sodium alginate (GO/SA) composite scaffolds were fabricated by a facile and eco-friendly method involving solution mixing and freeze drying. The obtained GO/SA scaffolds were characterized by X-ray diffraction (XRD), Fourier transform infrared (FTIR), and scanning electron microscopy (SEM). The porosity, water absorption, and compressive properties were also examined. FTIR analysis confirms the existence of hydrogen bonding between SA and GO. SEM results reveal that the composite scaffolds still present highly porous and interconnected structure despite of the incorporation of GO. Importantly, the GO/SA composites show significant improvements in compressive strength and Young's modulus as compared to neat SA. It is demonstrated that the mechanically strong GO/SA composite scaffolds with highly porous and network structure may be a promising candidate for tissue engineering applications.
