Abstract

Total joint arthroplasty bearings, which are most typically implanted in the human hip and knee, are composed of ultra high molecular weight polyethylene (UHMWPE). However, the bioactivity and mechanical performance of this polymer need improvement and several efforts have been made with this regard, in order to extend the material's service life and expand its biomedical applications. In this study, two distinct procedures for producing UHMWPE composites with varying cellulose nanocrystal loadings were used (CNCs). The microstructure, mechanical, and electrical properties of the resultant material were all thoughtfully examined. The research shows that by varying the concentration of CNCs and modifying the preparation procedures, it is possible to drastically alter the morphologies of composites and, as a result, their mechanical and electrical properties. Besides, the electrical measurements can be used as useful tool for studying the reproducibility of the manufacturing process.
