摘要

Composite materials have been widely used in the field of biomedical science. In this study, the optimal concentration of bioglass/carbon nanotubes (BG/CNTs) in a composite powder was investigated. The composite was produced using the sol-gel process. When CNTs were added, they provided a crystal nucleation site for BG nanoparticles and decreased the heat treatment temperature required (from 700 °C to 500 °C). Compared to the BG group, a suitable quantity of CNTs increased the pore size (12.67 nm) of the composite materials. Meanwhile, the BG/0.05 CNT group showed weight gain results and revealed a faster apatite formation rate after 3 days than other composites. The apatite layer (which increased in thickness from 1.69 μm to 12.51 μm) was observed using scanning electron microscopy after 7 days. Additionally, the proliferation of the MG63 cell line showed an excellent performance with some BG/CNT ratios. It should be noted, however, that an excessive number (>0.05 wt%) of CNTs as filler in a BG matrix reduces cell growth.
