“…It is also well documented that mineral acids cause p-doping of graphitic materials (graphite, carbon nanotubes and graphene) upon formation of a charge-transfer complex that shis the Fermi level of the doped material and increases its carrier concentration. 37,38 Both mechanisms, proton inclusion and charge-transfer, can take place in our system. The sensing units are also sensitive to other analytes despite the lower sensitivity as compared to HCl.…”

“…One report [114] has claimed that a relatively mild chemical doping process can be used to induce positive charges on GRM and increase GRM electrical conductivity without introducing severe defects into the sheets. Thermally expanded graphite (e-graphite) fluorinated by the intercalation of chlorine trifluoride (ClF 3 ) [115] was treated with acids before being re-dispersed in acetonitrile as positively charged graphene suspensions for EPD.…”

The Electrophoretic Deposition (EPD) of graphene-related materials (GRM) is an attractive strategy for a wide range of applications. This review paper provides an overview of the fundamentals and specific technical aspects of this approach, highlighting its advantages and limitations. Since obtaining a stable dispersion of charged particles is a pre-requisite for successful EPD, the strategies for suspending GRM in different media are discussed, along with the resulting influence on the deposited film. Most importantly, the kinetics involved in the EPD of GRMs and the factors that cause deviation from linearity in Hamaker's Law are reviewed. Side reactions often influence both efficiency and the nature of the deposited material; examples include the reduction of graphene oxide (GO) and related materials, as well as the decomposition of the suspension medium at high potentials. The microstructural characteristics of GRM deposits, and their degree of reduction, strongly influence their performance in their intended function. These factors will also determine, to a large extent, the commercial potential of this technique for applications involving GRM, and are therefore discussed here.
