Enhancement of Mechanical and Technological Properties of Uhmwpe Through Nanofiller Reinforcement

Key Points

This research focuses on how different nanofillers affect the mechanical and technological properties of UHMWPE.
Analyzed five types of nanofillers: MWCNT, graphene oxide, nano-Al₂O₃, nano-SiO₂, and surface-modified nano-MoS₂.
Incorporated nanofillers into UHMWPE matrix at loadings of 0.25–1.5 wt.% and assessed mechanical characteristics.
Evaluated effects on tensile strength, Young's modulus, wear rate, and sintering quality.
Optimum reinforcement at 1.0 wt.% GO increased tensile strength by 22% and Young's modulus by 26%.
Wear rate reduced by 48% compared to neat UHMWPE.
GO and MWCNT improved sintering quality and reduced compression ratio by 8–11%.

Abstract

The present study analyses the effect of five different nanofillers - multi-walled carbon nanotubes (MWCNT), graphene oxide (GO), nano-Al₂O₃, nano-SiO₂ and surface-modified nano-MoS₂ - introduced into the UHMWPE matrix at loadings of 0.25–1.5 wt.% on the mechanical and technological characteristics. The optimum reinforcement level was found to be 1.0 wt.% GO, which raised the tensile strength by 22 %, Young‘s modulus by 26 %, and reduced the wear rate by 48 % compared with neat UHMWPE. From the technological standpoint, GO and MWCNT additives improved the sintering quality and reduced the compression ratio by 8–11 %.
