The effect of different grafting extent of PBO‐MoS₂ hybrids on the tribological performance of TPI‐based composites at high temperatures

Abstract

The self‐assembled hybrids were synthesized as a kind of filler with the function of reinforcing and lubricating, by which can improve its dispersion in the matrix, and enhance the interfacial adhesion with the matrix. However, the effect of the amount of grafting on the hybrid properties is still unclear. In this study, a series of antiwear hybrids with different grafting amount were synthesized and further be used to reinforce thermoplastic polyimide matrix. The method of comparative analysis had been applied to analyze the microstructural morphology, thermal property, mechanical property, and high temperature tribological behavior of these composites. The results indicated that with the increasing grafting amount of MoS2 on the PBO fiber surface in a certain range, the integrated performance of the composite increases.

Impact of molybdenum disulfide diffused coir fiber on the physical, mechanical, thermal, and vibrational characteristics of polyester composites

“…Incorporating MoS 2 ‐diffused coir fiber into the matrix may achieve a more uniform dispersion, higher crystallinity index, and greater interfacial contact area, which restrict the thermal breakdown of composites and the release of volatile decomposition products 42 …”
