Study of electrical properties of graphene particles

In this paper, electrochemical exfoliation of graphite was used for fabrication of graphene particles. By using XRD, structure of sample was confirmed. Then, powder of particles was pressed by press equipment and converted to a tablet. By placing the tablet in an electrical circuit, I-V curve for the tablet was measured. Resistance, resistivity, and electrical conductivity were measured by four probe system. The results showed that fabricated sample has graphene particles but there are a few amount of graphite structure as well which can be increased percentage of graphene with systematic method. Therefore, a simple and cheap method is introduced for fabrication of grapheme particles.
