Abstract 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 (BT@C) hybrid nanoparticles were prepared by in situ oxidative self-polymerization and template carbonization. Then the BT@C was introduced into polyvinylidene fluoride (PVDF) scaffolds manufactured by selective laser sintering. On one hand, the ca...

Hydroxyapatite (HA) nanoparticles and silver (Ag) nanoparticles are expected to enable desirable bioactivity and antibacterial properties on biopolymer scaffolds. Nevertheless, interfacial adhesion between HA/Ag and the biopolymer is poor due to the large physicochemical differences between these components. In this study, poly L-lactic acid (PLLA) powder was first surface-modified with bioactive polydopamine (PDA) in an alkaline environment. Next, HA and Ag nanoparticles were grown in situ on t...

Abstract Antibacterial property for scaffolds is an urgent problem to prevent infections in bone repair. Ag nanoparticles possess excellent bactericidal activities, whereas their agglomeration restricts the full play of antibacterial property in scaffold. Herein, a mace-like nanosystem was constructed to improve their dispersion by in-situ growth of Ag nanoparticles on cellulose nanocrystal (CNC), which was labeled CNC@Ag nanosystem. Subsequently, the CNC@Ag nanosystem was introduced into poly-L...

Poly(L-lactide) (PLLA) is a promising bone repair material owing to its good biocompatibility and natural degradability, but its lack of bioactivity and insufficient mechanical property restrict its further application. Strontium (Sr) nanoparticles can endow materials with bioactivity, while reduced graphene oxide (rGO) nanosheets with excellent strength are commonly used in the strengthening phase. Nevertheless, both Sr nanoparticles and rGO nanosheets are prone to agglomerate in the matrix. In...

Abstract Biopolymer scaffold is expected to generate electrical stimulation, aiming to mimic an electrical microenvironment to promote cell growth. In this work, graphene and barium titanate (BT) was introduced into selective laser sintered poly-l-lactic acid (PLLA) scaffold. BT as one piezoelectric ceramic was used as the piezoelectric source, whereas graphene served as superior conductive filler. Significantly, the incorporated graphene enhanced the electrical conductivity and thereby increase...

Abstract Graphene oxide (GO) and mesoporous bioactive glass (MBG) are commonly used to improve the mechanical and biological properties of polymer scaffolds, respectively. Nevertheless, their single introduction to polymers may encounter problems with uneven dispersion due to nano-aggregation effects. In this work, a GO and MBG hybrid with micro-space network structure were prepared by a chemical reduction-coagulation method to solve these problems. GO and MBG were first uniformly mixed in an al...

The interfacial bonding between an inorganic clay and an organic polymer is weak although clay is usually used as a reinforcement phase in polymers. In this study, montmorillonite (MMT) was organically modified with (3-aminopropyl)triethoxysilane (KH550) and incorporated into poly(e-caprolactone) (PCL) to enhance the interfacial bonding in bone scaffolds. In detail, KH550 intercalated into the interlayer of MMT through cation exchange, and then one end of KH550 with NH3+ was adsorbed onto the ne...
