The different arrangements and combinations in which carbon can be configured produce a wide variety of compounds that have unique physical, chemical, and electrical properties. Graphitic nanomaterials including fullerenes (3D), one-dimensional (1D) carbon nanotubes and two-dimensional (2D) graphene-based sheets are attractive materials for next generation electronic devices. These carbon allotropes can behave as excellent conductors, semiconductors or even insulators depending on their geometries. Carbon-based devices offer several attractive features for use in next generation electronics. These materials can be dispersed and deposited using solution processes, and they can be easily integrated into tools and processes already developed for established materials, such as roll-to-roll manufacturing. Finally, they have long term chemical and temperature stability potentially unmatched by any other materials. In particular, graphene has been the subject of transformative research. However, due to the difficulty and the high cost associated in producing uniform single sheets of graphene, it hasn't been widely deployed yet. Exfoliated Graphene nanoplatelets (stack of graphene ranging from 1 to 15 nm thick) have emerged as a low cost alternative to single separated sheets of graphene, but their electrical, optical, chemical and mechanical properties in terms of electronic applications haven't been fully investigated. ****In this work, the objective is to fully investigate the electrical, chemical and mechanical properties of these graphene nanoplatelets mass-produced by Graphite Innovation and Technologies (GIT). We will assess the viability of this novel material system in integrated circuits by evaluating its electrical and its chemical compatibility with established technologies. Furthermore, as a 2D material, graphene nanoplatelets films are inherently mechanically flexible and could be integrated on various surfaces at minimal cost, allowing large area systems deployment. If they can mass produce platelet-based sheets, and these have similar properties to nanotubes or those of homogenous sheets, GIT will have a product that is significantly cheaper than either and will disrupt the graphite market place. The characterization of these materials may even reveal new properties of commercial value.****
