Severe phase separation was observed in blending nanodiamond particle (n‐DP) in poly(L‐lactide‐co‐ε‐caprolactone) (poly(LLA‐ co ‐CL)) scaffold. In this study we optimized the scaffold by the addition of 1–50% (w/w) polylactide modified n‐DP (n‐DP‐PLA) or benzoquinone‐modified n‐DP (n‐DP‐BQ). Composed by 10% n‐DP‐PLA, composite had 6 times higher E‐modulus in tensile test, whereas the maximum reinforcement can be higher than 15 times. However, n‐DP‐BQ composites conserved the mechanical properties, and thermal properties of the polymer substrate. The attachment, spreading and growth of UE7T13 cells on modified n‐DP composites were similar to poly(LLA‐ co ‐CL), and independent to n‐DP concentrations. In summary, a proper modified n‐DP is the key to reinforce poly(LLA‐ co ‐CL) for tissue engineering.
