Constructing core-shell structured BaTiO3@carbon boosts piezoelectric activity and cell response of polymer scaffolds

Piezoelectric composites have shown great potential in constructing electrical microenvironment for bone healing since their integration of polymer flexibility and ceramic piezoelectric coefficient. Herein, core-shell structured BaTiO3@carbon ([email protected]) hybrid nanoparticles were prepared by in situ oxidative self-polymerization and template carbonization. Then the [email protected] was introduced into polyvinylidene fluoride (PVDF)...
