What is it about?

Graphene is an allotropic of carbon in the form of a two-dimensional, atomic-scale, hexagonal lattic in which one atom forms each vertex. The structure of graphene is similar to other allotrope like graphite, charcoal, carbon nanotubes and fullerenes. Graphene is a 2D building block of other carbon materials with all other dimensionalities. It has the ability to convert into 0D Bucky balls, 1D nanotubes or 3D graphite. Graphene nanofluids have the applications in nuclear system cooling, space and defense, solar absorption, mechanical application, magnetic sealing, biomedical application, heat transfer intensification, electronic application, transportation, industrial cooling application and heat building and reducing pollution. So graphene nanofluids are the important subject of research area.

Why is it important?

Thermal management is a major concern for many technology that deals with high power. At the present time, there is a need of growing energy, precision manufacturing, miniaturization, nuclear regulations since critical economies demand high efficient coolants and lubricants. These issues can be overcome by the use of nanofluids which is the research area of interest of many research scholars. In this regard graphene nanoliquids have proven good results.


I was excited during writing this article since most of the activity about graphene started to happen in 2008. Therefore, this field is very young, active, and promising. Theoretically, graphene is an ideal material which is used for hydrogen storage. Experimentally, however, there is much to do to achieve these goals. It appears as a recurring pattern in all energy storage modes that the careful, rational nano-architectonic design and proper spacing of individual graphene layers is crucial for high-performance energy storage devices. The spacing dimensions are crucial for the functional design of graphenes. Proper graphene spacing not only prevents re-stacking and keeps the surface area of graphene high. It also provides nano-engineered space for molecules and ions to intercalate. There is a lot to be done as graphene based energy storage devices.
