Emission of fine and ultrafine nanoparticle aerosols from composites functionalized with Multi-Wall Carbon Nano Tubes (MWCNTs) subjected to sliding wear: the influence of matrix material

Key Points

The study explores how matrix material affects the emission of nanoparticle aerosols from MWCNT-reinforced composites under wear conditions.
Examined the tribological properties of polymer and cement composites made with MWCNTs
Analyzed the microstructure of the composites
Investigated aerosol emission in relation to different matrix materials
Aerosol emission patterns vary significantly based on the matrix material used.
Emissions could not be predicted by porosity or mechanical properties alone.
Different wear mechanisms lead to diverse effects of MWCNTs on aerosol release.

Abstract

Abstract While multi-wall carbon nanotube (MWCNT)-reinforced nanocomposites offer improved wear resistance, the health implications of released nanoparticle aerosols are a concern. This research aimed to understand the influence of matrix material on the tribological properties, microstructure, and triboemission of MWCNT-functionalized polymer and cement composites. Key findings reveal that aerosol emission cannot be predicted solely based on porosity and mechanical properties. The observed variations in MWCNT effects across different matrix materials are attributed to the distinct dominant wear mechanisms in each.
