Abstract
Process equipment and facilities are constantly facing the dilemmas of tear and wear. This manuscript introducing functionalized reduced graphene oxide with triazole moiety via click chemistry as a anti-wear additive. While this has been achieved successfully, full characterization of the new anti-wear additive material revealed it to be promising in ameliorating issues of wears. One of the merits of the synthesized material includes reduction of contact asperity as the lipophilic alkyl chain length increases. It has been tested to be functional when formulated as an additive in group III petroleum base oil. Accordingly, it shows an irregularity in renewable base oil. Following screening evaluations of the lipophilic alkyl chain lengths, the additive with twelve carbon atoms; functionalized reduced graphene oxide, rGO-T-C(12) was confirmed to stand out among others with the good reduction of friction coefficient and the least wear scar diameter of ~539.78 µm, compared to the base oil containing no additive.
Highlights
Increasing the lifespan of chemical process/energy facilities as well as engineering machinery is inevitably worthwhile
By carefully introducing lipophilicity and electron richness to reduced graphene oxide, the anti-wear additive material we develop emerges to tackle most of the issues mentioned in association to the conventional ones
The need to functionalize reduced graphene oxide (rGO) with lipophilic groups that would stay in the oil phase boosting dispersibility, and at the same time garnishing rGO with highly electron rich species favor the chemistry of metal surface contact to boost the tribological properties of tear and wear reduction for the anti-wear additive material
