Abstract

Abstract: In this study, a novel hybrid consisted of two‐dimensional graphene oxide (GO) and graphitic carbon nitride (g‐C3 N4 ) nanosheets were fabricated to improve the tribological performance of poly (phthalazinone ether sulfone ketone) (PPESK). The effect of the mass ratio of GO to g‐C3 N4 (1:1, 1:2, and 1:3) on the microstructure of GO/g‐C3 N4 was firstly studied. As the ratio was 1:2 (GO/g‐C3 N4 ‐2), the g‐C3 N4 could be homogeneously distributed on surface of GO, and the corresponding hybrid possessed many active sites. Moreover, the effect of GO/g‐C3 N4 hybrid, GO, and g‐C3 N4 on the tribological properties of PPESK matrix was explored systematically. Results showed that GO/g‐C3 N4 demonstrated more excellent reinforcing and lubricating effect than single GO and g‐C3 N4, especially for GO/g‐C3 N4 ‐2. More importantly, as the content of GO/g‐C3 N4 ‐2 was 0.1 wt%, the antifriction and anti‐wear performance of PPESK was improved by 77.28% and 96.9%, respectively. Moreover, the enhancement mechanisms of GO/g‐C3 N4 on the tribological behaviors of PPESK were clarified by analyzing the surface morphology of the composite and the counterpart. This work might provide the guidance for the design of a novel nano‐hybrid material applied in polymer self‐lubricating composites. Abstract : Microstructure of 2D/2D hybrid of GO/g‐C3 N4 ‐2 and its enhancing effect on the tribological behaviors of PPESK.
