Abstract
An interconnected porous Polyvinylidene fluoride/bioglass (PVDF/BG) scaffold was prepared by selective laser sintering. Its mechanical properties and bioactivity were reinforced by nanodiamond. The tensile strength successfully achieved to 59.61 Mpa, which increased by 23.01 % when the nanodiamond content was 1 wt%. It might be because nanodiamond particles dispersed in the matrix uniformly and had a good interface bonding with the matrix. Moreover, nanodiamond enhanced the scaffold bioactivity, which was proved by the biological mineralization and cell culture experiments. The nanodiamond reinforced scaffolds might have potential application for bone tissue engineering.
