Bio‐mineralized carbon natotubes (CNTs) were prepared by soaking carboxyl functionalized CNTs in a simulating body fluid (SBF). A uniform hydroxyapatite layer was precipitated on the outer walls of CNTs after 7 days of soaking. The results showed that, by addition of the as‐received CNTs and bio‐mineralized CNTs, the compressive strength of the calcium phosphate cement (CPC) increased by 24% and 120%, respectively. The modified interfacial bonding between the bio‐mineralized CNTs and CPC accounted for the significant improvement in the mechanical property by addition of the bio‐mineralized CNTs as compared with the as‐received CNTs.
