Exploring Nano-Graphene in Bio-Lubricants: Innovative Approaches to Reduce Friction and Wear Engineering Systems

The era of Nanomaterials is very promising and provides a friendly environment there by giving it a scope for lubrication. Although conventional lubricants such as SAE 20/30/40, machine oils and grease are very popular. The naturally available bio lubricants have been recognized and still there is a scope to explore the various combination of the lubricant to make work as efficient as the with existing lubricant. The nano compounds as additives are chosen predominantly to act as anti-wear, anti-friction, and to handle extreme pressure. Their nanoscale size, thermal stability, diverse chemical compositions, and rapid reactivity with surfaces without requiring an induction period is what that explores them to field of lubrication. These benefits translate into longer operational life for equipment, improved fuel efficiency, and extended maintenance intervals. This article highlights the advantages of nano graphene as emollient extracts and their variations in various path ways of lubrication. Additionally, it focuses on combining it with natural resources to thereby reduce the cost of lube oil. The nano graphene can be synthesized by using CVD, unzipping of CNT, Microwave-assisted exfoliation method, Ball milling method, and green synthesis. This investigation focuses on the different variation and concentration in lubricant oil to explore its rheological and wear properties
