Graphene’s general properties, and application of it in lubricating materials
Graphene is a solid lubricating nano material what is two-dimensional allotropic modification of carbon with only one atom thickness.
A thinnest film of graphene is hundred times stronger than steel, and occupies the leading positions among the materials with high lubricity.
Graphene was discovered not so long ago, however, its unique properties contribute to elevated interest and to implementing it into various spheres of industry such as electronics and optoelectronics, energy, production of composite materials as well as tribology, in particular, designing lubricating materials.

Graphene is obtained from graphite. Graphite has layer structure, and each of its numerous layers consists of hexagonal layers of carbon atoms. When the scientists managed to isolate a separate layer from the graphite structure, they obtained graphene. This very layer is a thinnest and the strongest material of all known ones.
GRAPHENE PHENOMENON: innovations available for everyone
The Modengy company develops a line of materials containing graphene. They are high-tech compositions characterized by convenient use and a wide range of applications.
The line under GRAPHENOM (GRAPHENE PHENOMENON) name will include liquid lubricating materials, greases and pastes with graphene in them, graphene coatings.
The designers of the new line have united innovative technologies and accessibility for a wide range of consumers in these compounds, both in aspect of easy use and concerning their price.
GRAPHENOM L100 multipurpose lubricating material
The first product of the new product line has become GRAPHENOM L100 multipurpose lubricating material with high penetration power.
The penetrative properties of its liquid base enable to effectively deliver components of the compound into the minimal gaps of the conjunctions, due to that this material is used to make dismantling of the jammed or corrosion affected connections easier. The product loosens and removes corrosion products, penetrates into the trouble area, and restores mobility of the mechanisms.
The main difference of GPAPHENOM L100 from the other known agents with high penetration power is ultralow friction.
Usually, the liquid penetrating lubricants help dismantle a connection, however, because of a very thin layer of oil, the lubricating properties of such agents are minimal.
Including graphene into their composition as well as specific components increasing strength and durability of the oil film radically improves lubricating properties under the most complicated friction conditions, in boundary lubrication mode.

Thus, GPAPHENOM L100 product combines in it penetration power enabling effectively dismantle connections affected by seizure and corrosion, as well as excellent lubricating properties on the top anti-friction materials level.
GRAPHENOM L100 advantages and properties are:
- Ultralow friction and effective wear reduction
- High penetration power, delivery of nano particles into most narrow gaps
- Steady lubricating film of prolonged operation
- High protective properties, powerful pack of anti-corrosive additives
- Ability to remove corrosion products and to restore mobility of mechanisms
GRAPHENOM L100 fits to be used in locks, hinges, chain gears, on weapon parts, furniture fittings, and in any other units requiring to restore their mobility, to provide them with effective lubrication without need in disassemble their mechanisms.
GRAPHENOM L100 composition, and its components functions
The components in GPAPHENOM L100 composition are thoroughly selected and balanced to achieve maximal efficiency and high operational properties.
The base of this material is mineral oil forming lubricating film and serving as a carrier of the other composition components.
Due to combination of organic solvents, this material has very high penetration power. It provides viscosity reduction of the lubricating product and possibility to fill in even the most narrow gaps and microcracks. Besides, the solvents effectively remove contaminations and residues of the lubricating materials used before.
The solvents used in GPAPHENOM L100 composition are dearomatized and virtually have no odor, are little aggressive towards plastics and rubber. That is why this multipurpose lubricant suits for a wide range of friction units with the parts made of different materials.
Graphene is the component that provides the composition with a cardinally low friction coefficient, especially in the boundary lubrication mode when an oil film breaks under high pressure and get incapable to prevent direct contact between interacting surfaces.

In process of friction, nano material fills in microroughness creating a smooth sliding surface.
To improve the properties of the product, a number of functional additives is added to the composition.
In the first place, it’s a powerful pack of anti-corrosive additives providing an effective protective film that neutralizes acid products-catalysts of corrosion processes, and also forms a protective passivation layer on the parts made of nonferrous metals.
Additionally, this component give excellent water displacing properties.
In the second place, to enhance penetration power of the compound, surface-active substances (SAS) are added to its composition. They abruptly reduce liquid surface tension, due to what it spreads easily over the metal surface and penetrates into even into the smallest pores.
The SAS also perform dispersing and emulsifying functions holding the agent in a suspended state.
As soon as the solvents are evaporated, adhesion intensifier in the compound starts ‘working’: it makes the oil film stronger and more durability, enhances its adhesion to the treated surfaces by enabling it to hold on even on the vertical areas as well as increases resistance towards water washout, and towards mechanical effects.
Conclusion
The series of GPAPHENOM lubricating compounds containing graphene nano material with super-lubricating properties enables to make high technologies available for everyone. These products are used all over: in household, in automotive machinery, at maintaining garden machines, bicycles, training equipment, tools, at productions, construction sites, etc.
In the course of time, GPAPHENOM product line will be enlarged with the new efficient products with the unique properties.
