Abstract
Abstract In order to improve the tribological performance of paper-based composites, graphene nanoplatelets (GNPs) and multi-walled carbon nanotubes (MWCNT) were introduced as lubricating fillers by paper making technique. Results showed that the thermal conductivity and tensile strength of composites increased by 47% and 51% respectively after adding MWCNT and GNPs, which is beneficial to reduce the thermal damage of composites and improve the mechanical properties of composites. Furthermore, the wear rate of modified composites greatly dropped from 3.59 × 10−14 m3 (N m)−1 to 1.24 × 10−14 m3 (N m)−1. The higher specific surface area of GNPs and the rod-like structure of the MWCNT play a positive role on the improvement of the tribological performance by forming friction film on the worn surface.
