High performance of MOF-structured lubricating material with nano- and micro-sized morphologies

In this study, the zeolitic imidazolate frameworks-8 (ZIF-8) with nano- and micro-sized morphologies was successfully fabricated by solvothermal method. The dispersibility of as-obtained ZIF-8 in oil was studied. As an application, the tribological behavior of the as-obtained ZIF-8 in the based oil was investigated. The nano- and micro-sized morphologies of as-obtained ZIF-8 were conductive to reduce the friction coefficient and wear, and raise the carrying capacity in the base oil. In addition, the friction reducing mechanism was proposed.
