Abstract 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 GO@Si-HA nanosystem was achieved by in-situ growth of Si-HA on GO, and then incorporated into PLLA scaffold fabricated by laser sintering techno...

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...

The insufficient mechanical strength and slow degradation rate of poly-L-lactic acid (PLLA) limit its applications in bone repair. In this study, zeolitic imidazolate framework-8 (ZIF-8), one typical metal organic framework, was introduced into a laser-sintered PLLA scaffold. The results showed that the ZIF-8 formed favorable interface bonding with PLLA due to its inherent hydrophobicity and abundant organic ligands. Meanwhile, it served as an efficient nucleating site and increased the crystall...

Abstract The poor interfacial bonding and resultant agglomeration of nanoparticles in polymer-based composite severely deteriorated their reinforcement effect. In this work, MgO nanoparticles (MgO-NPs) were surface modified with Poly (L-lactic acid-co-malic acid) (PLMA) to improve the interfacial compatibility in Poly-l-lactic acid (PLLA) scaffold manufactured by selective laser sintering. PLMA possess a hydrophilic end with carboxyl group (comes from the malic acid) and an l-lactic acid chain. ...

Abstract Poly‑l‑lactic acid (PLLA) is a promising bone repair material because of its good biocompatibility and natural degradability. Nevertheless, the poor mechanical properties and local inflammatory response limits its further application in bone repair. In this research, nano magnesium oxide (nMgO) was incorporated into PLLA scaffold manufactured by selective laser sintering technique. Results shown that nMgO with good affinity to PLLA could act as nucleating agent during crystallization pr...
