A strawberry-like Ag-decorated barium titanate enhances piezoelectric and antibacterial activities of polymer scaffold

Polyvinylidene fluoride (PVDF)/barium titanate (BaTiO3) composites are becoming increasingly attractive in bone repair since it combines the advantage of polymer flexibility and ceramic piezoelectric constant. Herein, silver (Ag) nanoparticles were decorated on polydopamine functioned BaTiO3 (Ag-pBT) by in situ growth. Then the strawberry-like structured Ag-pBT nanoparticles were introduced into PVDF scaffold fabricated by selective laser...
