Cobaltocene, known also as bis(cyclopentadienyl)cobalt(II) or even "bis Cp cobalt", is an organocobalt compound with the formula Co(C₅H₅)₂. It is a dark purple solid that sublimes readily slightly above room temperature. Cobaltocene was discovered shortly after ferrocene, the first metallocene. Due to the ease with which it reacts with oxygen, the compound must be handled and stored using air-free techniques.
A cobaltocene-based zwitterionic polymer and lubricating fluid, and methods of making and using the same
This invention belongs to the field of functional polymer materials, specifically relating to a cobalt-ceramic-based zwitterionic polymer and a lubricant, as well as their preparation method and application. The cobalt-ceramic-based zwitterionic polymer provided by this invention has cobalt-ceramic cationic groups and sulfonate anionic groups. The cobalt-ceramic groups have high potential energy and exhibit dynamic equilibrium adsorption and desorption behavior on steel surfaces, forming a protective layer through multiple interfacial interactions. The sulfonate groups have a strong affinity for water molecules, forming a highly hydrated interface. The cobalt-ceramic groups and sulfonate groups have low binding energy. Through the synergistic effect of the interaction between the cobalt-ceramic groups and the metal surface and the strong hydration of the sulfonate groups, excellent lubrication can be achieved, resulting in excellent anti-wear and friction-reducing effects on metal / metal friction pairs under different friction loads and frequencies.
