role in bone regeneration. In this study, we have synthesized polymeric hybrid
nanocomposites via free-radical polymerization from carrageenan/acrylic-acid/graphene/
hydroxyapatite. Porous hybrid nanocomposite scaffolds were fabricated through a freeze-
drying method to mimic the structural and chemical composition of natural bone. Fourier-
transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM) and water …
