Biomineralization on polymer-coated multi-walled carbon nanotubes with different surface functional groups

- Polymer-coated CNTs with different surface functional groups were prepared.
- Biomineralization of modified CNTs was performed using SBF.
- Surface functional groups play important roles in nucleation, growth and morphology of apatite.
- Positive acylamino group was helpful to obtain c-axis preferentially oriented CDHA from SBF.
