“…As we all know, 2D materials have a lot of research and applications because of their unique structures and friction properties. 16,18,19,41 However, due to the poor dispersion stability, their application in lubricants has not been effectively improved. The unique inorganic-organic hybrid structure of metal-organic frameworks is expected to change the status quo of two-dimensional materials in the field of lubrication.…”

Polyaniline/molybdenum disulfide (PANI/MoS 2 ) composites doped with hydrochloric acid were synthesised by in situ polymerisation and characterised by Fourier transform infrared spectrometer, thermogravimetric analysis and scanning electron microscope (SEM). The tribological properties of PANI/MoS 2 as composite lithium grease additive were investigated by MFT-R4000 currentcarrying friction and wear tester. SEM observed the surface morphologies of the wear scars, and energy dispersive spectroscopy and X-ray photoelectron spectroscopy analysed the element distribution and chemical state. The results show that PANI/MoS 2 composites have better tribological and electrical properties than PANI and MoS 2 additives alone and in the same proportion. Therefore, it can be concluded that MoS 2 and synergism of polyaniline modifier.

“…The use of surfactant as dispersion stability medium is the best method to decrease the size of the nanoparticle. Jiang et al [67] studied the dispersion stability of Oleylamine-modified WS 2 nanosheets in PAO oil over a wide range of temperatures. The authors found that nanoparticles with a size less than 10 nm have better dispersion stability than nanoparticles having a size greater than 10 nm.…”

With the advancement in the field of nanotechnology, various researchers have reported an improvement in the friction and wear behaviour of different lubricating oils by the addition of different nano additives. However, the stability of these nano additives remains a challenge. In this paper, the dispersion stability of various nano additives in lubricating oils has been studied in detail. The paper aims to summarize various dispersion stability theories and several methods reported in the literature to improve dispersion stability. Apart from this, a special focus has been laid to highlight the various surfactants used to improve the dispersion stability, particularly the tribological properties. The literature suggests that although a number of studies have been carried out to study the effect of surfactant addition on dispersion stability, however, future developments could be focused to improve the dispersion stability of the existing mono and hybrid nano fluids and their underlying mechanisms.Abbreviations: SWCNH, single-walled carbon nano-horns; PAO, poly alpha olefin; MoS 2 , molybdenum di sulphide; H
