Nano-montmorillonite-doped lubricating grease exhibiting excellent insulating and tribological properties

Tribological Properties of Polytetrafluoroethylene, Nano-Titanium Dioxide, and Nano-Silicon Dioxide as Additives in Mixed Oil-Based Titanium Complex Grease

Eight titanium complex greases (i.e., benzoic acid/stearic acid and sebacic acid/stearic acid titanium complex greases, and greases containing PTFE, or nanotitanium dioxide, or nano-silicon dioxide) were synthesized using 3-L reaction vessel. Their physical characteristics were characterized and their tribological properties were evaluated by using a four-ball tester. Chemical compositions of t...

Influence of Graphene Nanoflakes Addition on Grease Tribological Properties

Correlation between System Entropy and Structural Changes in Lubricating Grease

Lubricating greases are colloid disperse systems consisting of a base oil and a thickener (additional additives). The lubricant is modeled as a tribological system, and the reaction of a fluid friction stress is investigated. The energetic situation of the volume element is analyzed and the system entropy described. The description of the structural degradation and the used entropy was realized...

Synthesis & study of Polyethylene/Polyaniline/Montmorillonite ductile nano composites properties

Conducting polymers, because of their special properties, are used to introduce conductive polymeric composites. Also, clays have recently been used for preparation of polymer composites with enhanced mechanical and thermal properties. The aim of this work is to study the synergetic effect of the co-presence of conducting polyaniline and montmorillonite in the polyethylene matrix. Polyethylene ...
