The composite material of poly-(L-lactide) (PLLA) and carbon nanotubes (CNTs) were prepared. Itssurface morphologies and property were worked out by us-ing atomic force microscopy (AFM) and contact angle meas-urement. Moreover, the prime cytocompatibility was used to investigate the biocompatibility of the composite materialcontaining CNTs and the effects of CNTs on one aspect of cell function, cell affinity. The results obtained indicate that thecomposite material of PLLA and CNTs possesses good bio-compatibility for both the 3T3 fibroblasts and Oct-1 os-teoblast-like cells. The addition of CNTs will greatly affectcell affinity of the material, which may be disadvantage for the cell adhesion.
