Optical Properties and Applications of Graphene Nanoparticles

Graphene is in many respects a nanomaterial with its unique properties. Graphene is the thinnest material comprised of atoms. Graphene is the only one atomic layer thick and hence an almost ideal representation of a two-dimensional material in our three-dimensional world.

Graphene is a two-dimensional material made of carbon atoms with the shape of an hexagonal lattice. Graphene first isolated in 2004, by Andre Geim and Konstantin Novoselov in the University of Manchester by means of mechanical exfoliation of graphite. Since this time, graphene nanoparticles' properties and potential applications have been the object of study of many research teams around the world in almost all science areas. Graphene nanoparticles with an atomic thickness have excellent mechanical properties, electrical conductivity, optical properties, thermal conductivity and impermeability, which makes it attractive for many applications.

Graphene offers several advantages. Amongst all the properties of graphene, its optical properties will likely be the ones with most practical applications in the short-term, mainly in nanoscale applications .

As all we know there is an increase in data traffic in the years due to increase in number of internet and mobile devices users. Because all of us create big challenges in terms of data network management. When we think about bandwidth and energy consumption, today's data processing optoelectronic devices will no longer have the capacity to cope with future network requirements. Graphene nanoparticles can help us to solve this problem.

The other area where graphene nanoparticles can be used on a commercial scale is that in optoelectronics; specifically touchscreens, liquid crystal displays (LCD) and organic light emitting diodes (OLEDs). Graphene is an almost completely transparent material and is able to optically transmit up to 97.7% of light. It is also highly conductive, as we have previously mentioned and so it would work very well in optoelectronic applications such as LCD touchscreens for smartphones, tablet and desktop computers and televisions.

For our needs in the future, Graphene nanoparticles might be the key elements. Because Graphene nanoparticles have ultra-broad band optical response and excellent non-linear optical properties. And these properties make Graphene a fabulous material for developing next generation photonic and optoelectronic devices.

Carbon Nanotube Threads

Since its discovery, carbon nanotube (CNT) has attracted many interests in different technology fields due to its extraordinary properties. Properties such as, high strength, great electrical and thermal conductivity, light weight and flexibility made CNT one of the best materials for wide range of applications. However, from its name it can be understood that CNT is a nanoscale material which is very small to be applied for the production of daily products. Researchers all around the world are working on finding methods and techniques which could produce new materials with the extraordinary properties of CNT. Image retrieved from: https://worldindustrialreporter.com/strong-light-flexible-carbon-nanotubes-threads-with-ultrahigh-conductivity/ One of these research is focusing on the production of high strength threads that can be used in the manufacturing of fabrics, cables and ropes. An international group of scientists were able to produce a flexible conductive thread th...

Multi Walled Carbon Nanotube Dispersions

Carbon nanotubes (CNTs) have attracted enormous attention in recent years due to its unique physical, electronic, optical and potential applications in materials science and nanotechnology. The van der Waals interaction between tubes, however, makes CNTs aggregate in most organic solvents and aqueous solutions, which is the major limitation of their practical applications.Various approaches have been studied to alter the CNT surface to promote the dispersion of individual nanotubes and prevent their reaggregation. On the basis of this widely accepted viewpoint, numerous techniques such as covalent bonding, surfactant coating and polymer wrapping have been developed for surface modification or sidewall functionalization.These methods, however, are complicated, time-consuming and cause permanent damage to the CNT structure and properties of the surface, which produces residues of the dispersion agent for the final product.
