Abstract Scope |
The most popular biopolymer, ultra-high molecular weight polyethylene (UHMWPE) is used for articulating surfaces such as acetabular cup liners. On the other hand, wear debris formation leads to aseptic loosening of implants. Carbon nanotubes (CNT) are one of the most widely used nanomaterial in biomedical applications. To improve the tribological properties of UHMWPE, it is reinforced with two different lengths of CNT, long (10-20 µm) and short (1-2 µm). In the present work CNT based biocomposites with ≥ 98% densification were processed by compression molding at 220°C at 10 MPa pressure. The specific wear rate decreases by ~ 75 % from UHMWPE (~ 12.8 × 10-4 mm3/Nm) to UHMWPE-lCNT (~ 3.1 × 10-4 mm3/Nm). The MTT assay and cell proliferation confirmed the cytocompatibility of UHMWPE-CNT based composites against osteosarcoma like cell line (MG-63). Improved mechanical, tribological properties and cytocompatibility qualities, of UHMWPE-lCNT makes it an excellent candidate for biomedical applications. |
