Abstract

Abstract: Nano-sized graphite oxide (GO) sheets modified by 3-aminopropyltriethoxysilane (APTES) as lubrication additives were incorporated into polyethersulfone (PES) matrix aiming to improve the mechanical, thermal and tribological properties of this polymer. The incorporation of APTES-GO sheets significantly enhances the tensile and thermal properties of PES. Compared with the virgin PES, the PES composite with the APTES-GO addition of 1.0 wt% exhibits much lower friction coefficient (0.13) and wear rate (4.68×10 −15 m 3 /Nm). This can be attributed to the homogeneous dispersion of APTES-GO within PES matrix and strong interfacial adhesion between them, as well as the formation of uniform PES transfer film. Highlights: The friction and wear properties of PES are enhanced by the addition of APTES-GO. The PES composite with 1.0 wt% APTES-GO exhibits the best tribological property. The tensile property of PES is improved due to the incorporation of APTES-GO. Addition of APTES-GO can significantly enhance the thermal stability of PES.
