Abstract
Due to the unique self-assembling structure and rheological properties, supramolecular gel lubricants have become the third major type of liquid lubricating materials to supplement the lubricating oil and greases. Focusing on the solid-liquid interface compatibility between gelators and base oils, the molecular structures of gelators applicable to oil-based, water-based and extreme conditions base oils were summarized firstly. Furthermore, this review aims at exploring the relationships between the self-assembled structures of gelators and the gel-forming, rheological and frictional properties of gel lubricants. Based on the wide application of gel in various lubrication fields, the synergistic lubricating effect between gel lubricants and nanomaterials, film, textured surfaces were analyzed. The lubrication mechanisms from the solid-liquid interface compatibility between gel lubricants and solid lubricants were attempted to highlighted and revealed. Finally, the perspectives on the development of gel lubricants and corresponding composite lubricating materials were presented. It is hope that our discussion will be beneficial for the growing community of gel lubricant researchers.

期刊介绍：
The journal aims to publish papers at the forefront of nanoscale science and technology and especially those of an interdisciplinary nature. Here, nanotechnology is taken to include the ability to individually address, control, and modify structures, materials and devices with nanometre precision, and the synthesis of such structures into systems of micro- and macroscopic dimensions such as MEMS based devices. It encompasses the understanding of the fundamental physics, chemistry, biology and technology of nanometre-scale objects and how such objects can be used in the areas of computation, sensors, nanostructured materials and nano-biotechnology.
