One-step green synthesis of oil-dispersible carbonized polymer dots as eco-friendly lubricant additives with superior dispersibility, lubricity, and durability

Facile Synthesis of Lignin-Castor Oil-Based Oleogels as Green Lubricating Greases with Excellent Lubricating and Antioxidation Properties

“…When the temperature increased, the shear stress of castor oil and lignin-based oleogels gradually decreased. It is not difficult to conclude that the addition of lignin introduces many hydrogen bonds, and when the temperature rises, these intermolecular hydrogen bonds are destroyed …”

“…It is not difficult to conclude that the addition of lignin introduces many hydrogen bonds, and when the temperature rises, these intermolecular hydrogen bonds are destroyed. 39 It can be observed from the rheological analysis results (Figure 6b) that castor oil is a Newtonian fluid, as the relationship between shear stress and shear strain rate obeys Newton's law of internal friction or Hooke's law (Figure S5). In contrast, lignin-based oleogels are pseudoplastic fluids due to their internal irregular order at rest, resulting in higher viscosity (Figure 6b) and resistance to flow.…”

Size-Regulated Metal–Organic Frameworks with Mercaptobenzothiazole for Ga-Based Liquid Metal Encapsulation: A High Performance Oil-Based Additive

“…53 Moreover, this direct contact generated a significant amount of abrasive debris, further accelerating wear. 54 However, the addition of GLM or GLM-TA created smaller pits and tiny wear debris on the worn surface. This suggested that the GLM was capable of forming a protective film during friction, preventing direct contact between the friction pairs.…”

“…Destruction of the oil film during the friction process led to direct contact between the friction pairs and exacerbated wear . Moreover, this direct contact generated a significant amount of abrasive debris, further accelerating wear . However, the addition of GLM or GLM-TA created smaller pits and tiny wear debris on the worn surface.…”

In Situ Graphene Formation Induced by Tribochemical Reaction for Sustainable Lubrication

“…Meanwhile, the lubrication ability of lubricating oil requires further improvement due to the more drastic actual application conditions. Various materials including carbon and its derivatives, metals, metal oxides, sulfides, rare-earth compounds, nitrogenous heterocyclic compounds, borates, and ionic liquids, are utilized as additives and added into lubricating oil to enhance its lubrication performance. Thereinto, carbon materials acquire more attention in virtue of their excellent mechanical properties, superior thermal and chemical stability, environmentally friendly property, and peculiar self-lubricating property .…”
