Thermal-Controlled Frictional Behaviour of Nanopatterned Self-assembled Monolayers as Triboactive Surfaces

Abstract: Friction is an important limitation of energy efficiency performances of MEMS/NEMS but is, in the same time, a great opportunity for harvesting energy by designing optimized Tribo-Electric Nano-Generators (TENG). Thus, frictional behaviour can be accurately controlled in real-time by using thermally sensitive periodic patterned self-assembled monolayers of n-octadecyltrichlorosilane (OTS) grafted on MEMS surfaces. Nanopatterns are currently used in order to limit the wear rate without modifying the frictional … Show more

“…A natural extension of such studies involves charged constituents, particularly in suspensions [5,6], which are ubiquitous in lubricants and are readily manipulated by external electric and magnetic fields [7]. Examples include tailoring of electrolyte lubricants for custom response to electric and magnetic fields, environmentally friendly ionic liquid batteries, automatic friction and braking controls in mechanical systems, tribotronic micro-electro-mechanical systems (MEMS) devices for electrical power generation, thermally controlled friction via surface nanopatterning, and tunable viscosity and wall slip via polarizable electrodes [8][9][10][11][12]. This emerging field is referred to as "tribotronics", and is defined as the "active" or "smart" control of friction by combining machine elements with electronics [13][14][15][16][17].…”
