Surface‐modified ZnS nanoparticles have been fabricated, and the morphologies and crystalline structures of the powder have been characterised by transmission electron microscopy, X‐ray diffraction and Fourier transformation infrared spectrum. The tribological properties of the surface‐modified ZnS (SM‐ZnS) nanoparticles as an additive in PEG400 were evaluated with a four‐ball tester. It was found that the as‐prepared SM‐ZnS nanoparticles had a very narrow size distribution, with the average diameter about 5–10 nm. The SM‐ZnS nanoparticles as the additive led to an obvious improvement in the anti‐wear and friction‐reduction properties of the synthetic PEG400. Analysis indicated that a boundary film was formed during the friction process. Copyright © 2014 John Wiley & Sons, Ltd.
