Abstract
The structural, morphological, mechanical characterization and cells interaction of ATZ (Alumina ToughenedZirconia)-UHMWPE composites containing 2.5 wt% of ceramicfiller obtained with different dry-mixing tech-niques are discussed, in order to assess their feasibility as biomedical supportive function materials. The resultsindicate that, by changing the dry-mixing techniques used for preparing composites, it is possible to tune thestructural and morphological characteristics of the composites that, in turn, affect the mechanical parameters.All the composites show good cell interaction and promote higher cell viability at 24 h than the unfilledpolymer. The biological behavior is not directly correlated with wettability and microroughness, but it seemsdependent on the presence of ATZfiller.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
