Because of their intrinsic properties, carbon nanotubes (CNTs) have been suggested for biomedical applications. We studied the anti-adherent performance of two ultra-high-molecular-weight polyethylene (UHMWPE) surfaces which contains 3% multi-wall CNT variant (MWCNT): Nanocyl/UHMWPE and Arc/UHMWPE. These surfaces were obtained by hot pressure forming after mechanical mixture. Additional nanoindentation studies were performed and hardness and stiffness were determined. Mechanical properties of the MWCNT/UHMWPE composites were also compared to raw UHMWPE and correlated with their anti-adherent performance. Comparing with UHMWPE, Nanocyl/UHMWPE was the least adherent surface. Bacterial adherence was also significantly reduced in Arc/UHMWPE for four strains. [GRAPHICS] .
