Study and Evaluation on Dispersion of Molybdenum Disulfide in Aqueous Solution

Abstract

The effects of surfactants, such as sodium oleate soap, triethanolamine oleate, MOA, OP-4, had been studied for the dispersion of molybdenum disulfide (MoS₂) in aqueous solution. And the lubricating property of the water dispersion system had been observed by four-ball tester. The results show that sodium oleate soap, MOA and OP-4 have the excellent composite effect for the dispersion of MoS₂ aqueous solution, and having a best ratio (wt%) for sodium oleate soap: MOA: OP-4 = 1: 1.8: 2.
