Ultra high molecular weight polyethylene is commonly used in joint replacements related to orthopaedics due to excellent properties of it, but its limited resistance to wear necessitates improvements to reduce revision surgeries. This study explores reinforcing ultra high molecular weight polyethylene (UHMWPE) with multi-walled carbon nanotubes (MWCNTs). Mechanical and thermal properties were analysed per ASTM standards. Results show that MWCNT incorporation enhances UHMWPE's thermal properties, with crystallinity increasing from 52 to 64% and weight loss decreasing from 4.3 to 1.3% (DSC and TGA analyses). These findings highlight the potential of MWCNT-reinforced UHMWPE to improve durability and extend the lifespan of arthroplasty devices.

摘要

Ultra high molecular weight polyethylene is commonly used in joint replacements related to orthopaedics due to excellent properties of it, but its limited resistance to wear necessitates improvements to reduce revision surgeries. This study explores reinforcing ultra high molecular weight polyethylene (UHMWPE) with multi-walled carbon nanotubes (MWCNTs). Mechanical and thermal properties were analysed per ASTM standards. Results show that MWCNT incorporation enhances UHMWPE's thermal properties, with crystallinity increasing from 52 to 64% and weight loss decreasing from 4.3 to 1.3% (DSC and TGA analyses). These findings highlight the potential of MWCNT-reinforced UHMWPE to improve durability and extend the lifespan of arthroplasty devices.
