Abstract

Due to the PMMA resin has a widespread in dental restorations, the current study focused on assessing the tribological properties of the composite filled with nano-filling. The hybrid nano-filler used in this research is graphene and TiO2 nanoparticles. Loading filler amount of TiO2 nanoparticles 0.25, 0.5, and 0.75 wt. %, while graphene adds with amount of 0.5 and 1.0wt. %. The reciprocating tribometer was used to perform the tribological properties of the composites. Moreover, the hardness was evaluated via durometer Shore D. It was found that a good enhancement in the mechanical and tribological properties of PMMA composites. According to experimental results, it can conclude that, PMMA nanocomposites with filler content of 1.0 wt. % of graphene and 0.25 wt. % TiO2 nanoparticles recorded the best wear resistance performance comparing with pure specimen.
