Special Issue Information

Dear Colleagues,

This Special Issue aims to present original research articles and reviews on colloidal lubricants and interfacial tribology. Colloidal lubricants including liquid dispersions, gels, and greases have found extensive tribological applications in recent decades. By generating a complicated interfacial “tribofilm” capable of providing either physical or tribochemical lubrication, they can effectively reduce the friction and abrasion between two contacting surfaces to a satisfactory level. Although a number of significant research advances concerning the tribological and interfacial properties of colloidal lubricants have been achieved, the design and preparation of high-performance and eco-friendly base oils and additives, the homogenous dispersion of diversified additives in base oils, the formation and composition of interfacial tribofilms, the tribochemical mechanism of colloidal lubricants, and in-time or in-space lubrication control remain challenging in this field. This Special Issue of Lubricants focuses on the lastest progresses in friction and wear mechanisms, new methodologies for tribological and interfacial analyses, and the development of new-type colloidal lubricants. Articles in this issue are applicable to any type of colloidal and interfacial materials used for tribological applications.

This Special Issue is dedicated, but not limited, to original papers and reviews regarding the following topics:

  • Design and preparation of novel lubricating base oils and lubricant additives;
  • Tribological properties and interfacial behavior of colloidal lubricants;
  • Environmental adaptivity and interfacial friction control of colloidal lubricants;
  • Friction and wear mechanisms of interfacial tribofilms;
  • Methodology for analysing composition and interfacial property of tribofilms.

Abstract
Hydrogels have received extensive attention as functional lubricants because of their excellent anti-friction and anti-wear properties, tunable tribological performances, and effectiveness in alleviating lubrication failures caused by the creeping or leakage of conventional liquid lubricants owing to their semi-solid nature.

Hydrogels have received extensive attention as functional lubricants because of their excellent anti-friction and anti-wear properties, tunable tribological performances, and effectiveness in alleviating lubrication failures caused by the creeping or leakage of conventional liquid lubricants owing to their semi-solid nature. This review summarizes the current research advances in hydrogel lubricants fabricated with various organic and/or inorganic gelators, including organic polymeric or supramolecular hydrogels, inorganic particles-based hydrogels, and organic polymer-inorganic particle hybrid hydrogels. We illustrate not only the design strategies for constructing high-performance hydrogel lubricants but also the tribological behavior and mechanism of different types of hydrogel lubricants and their potential applications in industrial and biomimetic fields. Corresponding outlooks and suggestions for future studies have also been proposed. Full article
