A co-dispersion nanosystem of graphene oxide @silicon-doped hydroxyapatite to improve scaffold properties

Poly l-lactic acid (PLLA) was limited in the further orthopaedic application due to its insufficient mechanical property and poor bioactivity. Graphene oxide (GO) is an effective reinforcement, whereas silicon-doped hydroxyapatite (Si-HA) possesses excellent bioactivity, but either GO or Si-HA tends to aggregate in PLLA matrix. In this study, a [email protected] nanosystem was achieved by in-situ growth of Si-HA on GO, and then incorporated into...
