Abstract

Inclusion of 25 wt% of UHMPWE particles to SU-8 improved the tribological properties and restricted crack propagation within the matrix. Further adding 0.2 wt% and 0.5 wt% of hyaluronic acid (HA) reduced friction and wear. Worn surface morphology revealed that the HA-filled composite has less damage and smoother appearance than the composite without HA. The phenomenon of HA lubrication was attributed to the lubricating film formation ability of HA. Also, HA induced hardness has positively influenced the wear rate of SU-8 composites. These promising results of SU-8/UHMWPE/HA composites make them potential candidate as future hip implant material.
