摘要：

The tribological properties of the self-lubricating polymer were improved by strengthening the properties of the transfer film. The graphene oxide (GO) reinforced polytetrafluoro-ethylene (PTFE)/poly-p-phenylene terephthamide (PPTA) composites (GPPs) were prepared by dual-size synthesis. The tribological properties of GPPs were studied on a ball-on-disk tribometer. GPPs have low friction coefficient (minimum = 0.061) and hydrophobicity (maximum = 137.1385 degrees). The structure-property relationships and the practical effect of transfer film enhancement induced by GO were revealed. We attempt to provide guidance for the GO reinforced self -lubricating polymers design. Finally, in light of the excellent properties of GPPs, this study provides guidance for the GO reinforced self -lubricating polymers design.(c) 2023 The Author(s). Published by Elsevier B.V.
