Article Description

Currently, the conductive grease has problems such as unstable conductivity and large wear volume. This article used an in-situ synthesis method to synthesize a base conductive grease with PAO 10 as base oil, oleic acid and melamine as thickener. The complex conductive grease was further prepared by doping MWCNTs-OH into the base conductive grease. The experiment found that the complex conductive grease's anti-wear and anti-friction properties improved by 72.23 % and 27.16 %, respectively, with respect to the current-carrying condition. The contact resistance is 27.12 % lower than commercially available conductive grease. This method of reducing the contact resistance (ECR) and friction coefficient (COF) of conductive grease through hydrogen bonding shows excellent application prospects in the current-carrying friction direction.
